US Senator Rick Scott (R-Fl) this morning said that "we are not enforcing immigration laws". (for context, the discussion centered around the southwest border).

I've tried to find examples of this failure to enforce the law, without success. Can anyone provide examples? I am particularly interested in deliberate and elective dereliction by Federal authorities to enforce immigration law.

Second question would be this: IF the law is not being enforced (by those who are authorized and charged to enforce), why are these people not being discharged or fired?

BTW, the president has repeatedly said that the existing immigration laws are weak and "stupid", so I'm not asking about that. Failure to enforce the existing laws is an entirely different matter.

No law, immigration or otherwise, is ever completely enforced. Law enforcement has limited manpower so it has to choose priorities. And trying to zealously enforce any particular law generally has negative side effects. If you want to zealously enforce a law against littering, for example, I may be less likely to cooperate with the police investigating something more important if my testimony involved a receipt blowing away in the wind. So with any law, those charged with enforcement have some latitude to decide on policies that balance manpower against the harm the law is intended to address against the side effects of zealous enforcement.

There are lots of debates about how to prioritize where to direct resources. Do you want to focus resources on every person that violates immigration laws equally? Or do you want to prioritize those that also violate other laws? Most people are going to agree that they'd rather law enforcement focus on deporting killers and rapists over those that have never broken the law. But what about minor violations of the law-- if the police stop someone for speeding and discover they violated immigration laws, do you want them to arrest the person? Or ignore the immigration violation? If you decide to let the speeder go, you're failing to enforce immigration law. If you arrest and deport him, you're creating a situation where large numbers of people will avoid the cops at all costs because some of their family and friends have violated immigration laws and any sort of police investigation might lead to their deportation. Do you want the cop to make the call or do you want someone higher up setting a policy? The debates on DACA and sanctuary cities are really debates about how to prioritize enforcement manpower and to what extent those decisions should be made explicit.

Even when you have agreement on enforcing laws, there are questions about how and where to devote resources. You can always stop more people from coming over the border illegally by deploying more agents and more technology but you'll never stop everyone. How many people do you want monitoring the deserts on the southwest border? If you're a hard-liner, you can always add more agents, more barriers, more technology and reduce inflows. And you can argue that failing to devote enough resources to the task is a failure to enforce the law. If you want to zealously enforce speeding laws, you need more troopers manning speed traps. If you want to zealously enforce immigration laws, you need more agents monitoring the border. You can add more people to look for people working under fake social security numbers or employers that hire those that aren't legally allowed to work here. But that has downsides. If you use something like eVerify to screen for people that aren't allowed to work here, some legal workers are going to get caught up unintentionally and denied jobs until they can get the system fixed. If you go after employers, you're going to catch some employers that innocently accepted fake documents as well as those that were intentionally trying to circumvent the law.

In short, enforcing the law is generally not a boolean thing. There is no such thing as "Yes, this law is being enforced." There are always trade-offs. There is always more or less that could be done to enforce the law. There are always more resources that could be devoted to law enforcement. Much of the role of the executive branch is to determine which of those trade-offs make sense. And wherever the executive comes down, someone is going to say they're too hard and someone is going to say they're too soft.

Here's an example of self-declared selective enforcement at local level (from Oct last year, so it should be relevant enough):

As officials unveiled a series of public service announcements on the importance of reporting crime, Orange County Undersheriff Don Barnes, who is running to be elected sheriff next month, assured residents Tuesday that his agency is not enforcing immigration laws.

The television public service announcement are meant to assure immigrants living in the country illegally that law enforcement will not arrest them if they report a crime or are victims of a crime.

"There is some rhetoric in local media that law enforcement" has been enforcing immigration laws, Barnes said at a news conference at the Mexican consulate's office in Santa Ana.

"That is not true," he added. "We do not enforce immigration law. We have never enforced immigration laws and we will not enforce immigration law on the street level."

Barnes said any indication otherwise "sends a dangerous message to the community and erodes trust" in law enforcement.

"We don't ask for immigration status" when responding to any reports of a crime, Barnes said.

"If you call for help we will be there for you," he said.

"We will not be subjecting anyone to any inquiry regarding your immigration status."

Barnes, however, acknowledged that his department has cooperated with federal immigration authorities when it comes to transferring some Orange County jail inmates to a federal facility for immigration enforcement.

But Barnes pointed out that of 58,129 inmates booked last year only 580 were released to Immigration and Customs Enforcement officials.

"Those handed over to ICE are serious offenders."

And a similar one:

Following statements made by the President-Elect and various other governmental officials concerning the enforcement of immigration laws, there have been an increasing number of questions raised regarding the Santa Monica Police Department's official position on immigration enforcement.
The Santa Monica Police Department (SMPD) has a decades old policy and practice of leaving the enforcement of immigration violations to the federal authorities. This policy has been in effect because, similar to other municipal law enforcement agencies, we are sensitive to the principle that effective law enforcement depends on a high degree of cooperation between the SMPD and the public we serve. SMPD officers understand that the U.S. Constitution guarantees equal protection to all persons within its jurisdiction, in this case, to include the City of Santa Monica. Furthermore, we understand that all individuals, regardless of their immigration status, must feel secure in the knowledge that contacting law enforcement will not make them vulnerable to deportation. One of the primary reasons SMPD does not enforce immigration violations is to encourage those undocumented community members who are crime victims or witnesses to feel more at ease when coming forward to report occurrences of crime to the police. By not enforcing the immigration laws, SMPD encourages willing participation in our community safety efforts by those who might not otherwise come forward for fear of having to disclose their immigration status and risk deportation. As has traditionally been the case and will continue to be, SMPD officers do not inquire as to a person’s documented status; the only exception to this practice is if the person’s immigration status is materially relevant to another criminal offense or investigation, such as human trafficking, terrorist threats, etc.

And for some background:

In 1996, Congress authorized the attorney general to make agreements with state and local governments permitting them to enforce immigration laws. But before Sept. 11, lack of state and local interest, coupled with opposition by pro-immigrant and business groups, kept agreements from being struck.

Since the federal government can't just fire the local and state officials but has to make deals (arrangements) with them, you can see why this is not a simple "you're fired" matter. Trump tried to put financial pressure on "sanctuary cities" as they came to be known, but eventually gave up after legal challenges:

A judge in one of the cases against the Justice Department also said that local jurisdictions' decision not to assist federal immigration officers is not an obstacle to that immigration enforcement effort. Overall, courts have said that the administration cannot place conditions on the grants.

And since the confusion seems to revolve around the word "obligation" in the OP's formulation, I'll recall that selective enforcement of laws is legal in the United States.

Although the present administration has chosen to take a hardline approach on immigration enforcement, it can only do so (by itself) at federal level (via executive orders etc.) The discussion on selective enforcement is nothing new, since most previous administrations were less hardline, e.g. a 2014 article discussed:

Would President Barack Obama, by refusing to enforce the immigration laws against millions of undocumented immigrants, be engaging in “domestic Caesarism,” as Ross Douthat charges? The New York Times columnist thinks that “the granting of temporary legal status” violates the Constitution because Congress has itself refused to issue amnesties or offer a path to citizenship. [...]

Millions of illegal immigrants have lived in the United States for decades, under a semi-official policy that allows them to stay as long as they don’t commit serious crimes—and that, in many cases, allows them to obtain drivers’ licenses. The main effect of Obama's proposal would be to officially recognize current practice. The president cannot suspend or change the law: When he leaves office, the law will remain the same as it was, and the next president will be free to enforce it or not.

The executive branch spends a lot of time not enforcing laws. Congress has illegalized an enormous amount of activity without giving the president the resources to enforce the laws, so the executive has no choice but to make a list of priorities and devote its attention to law violations that, in its opinion, are the most serious. Thus, the IRS doesn’t audit paupers very often. The Justice Department ignores a lot of anticompetitive behavior that might raise prices a bit but not much. The DEA focuses on criminal syndicates rather than ordinary drug users, although both violate federal law. And so on.

Nearly all of this non-enforcement takes place with implicit congressional acquiescence; once in a while, Congress complains because the president’s priorities are not the same as its own. But the president has no obligation to listen to these complaints. [...] This is the separation of powers. People like Douthat wrongly think that separation of powers means that the president must do what Congress decides. That’s not the principle of separation of powers; that’s the principle of legislative supremacy, embodied in parliamentary systems like Britain’s, which America's founders rejected.

And neither do the local (or state) governments have to listen to moans from Congressmen, as far as I know. Federalism and all that.

Presumably Congress could pass a law allowing the Federal Government to pursue or punish local-government non-enforcers in some way. But until and unless that happens (on immigration matters)... there's no obligation for the local governments to enforce immigration law. Which doesn't mean however that these locals are enforcing the immigration laws.

The situation of marijuana laws in the US provides a pretty good analogy:

“that state decriminalization and even authorization of marijuana possession and use do not necessarily conflict with the federal criminal prohibition. If state officers were in fact responsible for enforcing federal law, or if the federal statute could and did require that state laws include comparable prohibitions, then a different situation would present itself. But state officers cannot be compelled to enforce federal law, and the federal statute does not require—and likely could not mandate—that state laws contain comparable marijuana prohibitions.”

“It’s not that the state laws are attempting to nullify the Controlled Substances Act. The federal statute still applies to the activities that it specifies, is still enforceable by federal agents, and can still lead to federal prosecutions, convictions, and sentences. It is simply that the states themselves are no longer criminalizing some of these activities. And while that may disappoint federal expectations, and even conflict philosophically with the federal outlook, that circumstance by itself does not give rise to preemption under the Supremacy Clause.”

At a high level there are many ways to not enforce laws. Off the top of my head:

It can be deliberate by directly and deliberately disobeying the law. Think rank and file doing illegal things. This engages the personal liability of those who do it, and that is why managers told their rank and file to ignore what Trump told them to do in El Paso last week.

It can then be deliberate by way of juggling with priorities and turning a blind eye on what's low priority. Think police officers turning a blind eye when they notice a petty crime like smoking a joint on their way to something more important. Or think you having the police file a report because someone stole your bike -- they know they won't look for it, it'll almost certainly dawn on you as they file the report that they won't look for it, and yet they're supposed to, but you also know your stolen bike is probably lower priority than just about everything else. And for an example of laws not being followed, look no further than the Trump organization.

A variation of the latter is when middle or high management sets something as very high priority and allocates resources based on that. A fictional but dramatic example of this is the Die Hard movie (3?) where police are tasked with finding a bomb in a school, while leaving the streets unkempt, thereby essentially allowing a bank robbery to take place in Wall Street. More concretely, picture NYC police prioritizing chasing petty crimes towards the end of the last century, on a backdrop of growing Wall Street accounting control fraud. I'm not so privy with US immigration laws or what's going on at its Southern border but I suspect this is what Trump was ranting about. And in an immigration policy enforcement scenario, you could easily imagine officers being told to patrol one section of the border a lot more than another ... or the 2011 Morton Memo that instructs them to prioritize chasing criminals (h/t Fizz).

Lastly, it can be at a legislative level, by simply defunding bespoke agencies so they're unable to enforce the law. This is basically what happened to the IRS. Or ObamaCare. Without the means you simply can't enforce the law. And even when agencies are funded, there's never enough means to enforce the law fully.

Laws say (among other things):

1. 
   

   If someone is deported, they can't come back.

   
   
   

   But people who have been deported do come back, even multiple times. E.g. Kate Steinle's murderer.

   
   


2. 
   

   If someone requests asylum, they must demonstrate that they fear prosecution in their home country for "one of five protected grounds: race, religion, nationality, political opinion, or particular social group." (Wikipedia)

   
   
   

   But two subproblems:

   
   
   
   • Not everyone appears for their asylum hearing.
   
   
   • People who come for economic reasons are getting asylum as refugees.
   
   


3. 
   

   Employees in the United States must demonstrate that they have a right to work in the US.

   
   
   

   But some undocumented immigrants use forged documents. This is illegal, but there is no enforcement mechanism. The companies are expected to detect the forgery.

   
   


4. 
   

   If someone is committing a crime (e.g. being illegally present in the US), then local authorities should detain that person until the federal government can take custody.

   
   
   

   But sanctuary cities don't do that.

   
   

So when Senator Rick Scott says that the laws aren't being enforced, he may mean (depending on context):

1. The border is not being enforced. People are crossing without permission.


2. People are not being made to appear for their asylum hearing.


3. Economic migrants are receiving refugee spots.


4. Document forgeries are not being detected.


5. Sanctuary cities are not detaining people for federal authorities.

Donald Trump just fired a bunch of people at Homeland Security. So one response would be that people are getting fired. Another is that the people who are failing to enforce the law aren't employees of the federal government and therefore can't be fired by the federal government. For example, the people in sanctuary cities that fail to respond to detainer requests are municipal employees.

There are of course changes in the law that would make enforcement easier:

1. More border resources. E.g. a wall or other physical barrier, increased surveillance, more law enforcement agents or military help (controversial).


2. Detain asylum seekers until their hearings.


3. Nationwide, mandatory E-Verify to shift the burden of detecting forgeries from employers to the government.


4. Add punishments for not complying with detainer requests. E.g. remove qualified immunity from civil and criminal suits; criminalize non-compliance with fines and/or prison sentences; fine or reduce payments to municipalities.

But you said that you didn't want to talk about law changes.
