I hope this kind of thing is the only prodding cities and states need to go ahead and arrest these criminals. I think many immigration officers have shown restraint for fear of the ACLU or someone coming down on them. Maybe if they see that, yeah, one CAN do his job and actually make a difference, and the usual suspects can only bitch and moan, we might make some progress.
It would help, of course, if the president made a comment in support of this kind of thing, though I'm not betting on it.
