Go ICE !!
Kick their a$$e$ !!
While I don’t approve of the “sanctuary city” nonsense, there is a reason for not arresting people at a courthouse.
If illegals become afraid to deal with law enforcement and the courts, then they become part of a subculture which is afraid to report crimes against them; or to be witnesses to crimes.
And that means, for some cities, a population of hundreds of thousands which is unwilling to step forward as witnesses. And that in turn makes for more crime, not less.
