Tell that to the guy who is rotting in the El Salvador's torture prison despite having official protection from the US court, not just self-declared policy of ICE like that above. Especially considering how shady ICE and its people are, bottom of the barrel of federal law enforcement.
So now instead of appearing in court and face their consequences if guilty, they are motivated to flee and evade even if innocent of the crime they are appearing in court for?
From the criminal complaint in this case:
"I also am aware that pursuant to its policies, which had been made known to courthouse officials, the Milwaukee ICE ERO Task Force was focusing its resources on apprehending charged defendants making appearances in criminal cases – and not arresting victims, witnesses, or individuals appearing for matters in family or civil court."
So it sounds like they take this into account. As for why they make arrests at the courthouse:
"The reasons for this include not only the fact that law enforcement knows the location at which the wanted individual should be located but also the fact that the wanted individual would have entered through a security checkpoint and thus unarmed, minimizing the risk of injury to law enforcement, the public, and the wanted individual."
Makes sense. Seems like they have weighed the risks and advantages of this and come up with a reasonable approach.
