No the Fed cannot force state/local enforcement of Federal law ... that doesn't mean it's prudent to reject it.
It depends on the specific situation.
After discussions with a sheriff, a DPS officer, a city cop and my local marshall ... I was right in the answer to the question I thought I'd read. I was wrong in understanding the question.
I don't know what question you thought you read, so I can't comment.
What's happened under this administration is that ICE has been heavily restricted from that "taking custody" of an offender ... that resulted in the tragic event of Kate Steinle's death (and many many others) ... and it clearly SHOULDN'T have had the opportunity to occur. So, there's been a logistical problem with holding these perpetrators as the current POTUS/staff/et al have made it unnecessarily difficult for one of those State/Locals to detain long enough for the Fed to arrive.
My expectation isn't that patrolmen should be detaining folks after a speeding citation to await the arrival of a Treasury officer to enforce the collection of an IRS fine ... we're talking about people who have posed physical threats. There's no articulation which makes proper the release of an illegal immigrant who's been deported 5 times and has committed violent offenses while being in the country illegally.
As I've said previously, we need common sense on the issue. An illegal immigrant shouldn't be turned over to ICE just because he or she reports a crime or commits a minor traffic offense. (DWI is not a minor traffic offense.) However, when one is incarcerated for a serious crime, ICE should be notified of his release date and should take him into custody for deportation as soon as he walks out the door of the jail or prison. That would have prevented the Steinle death.
