Subject: Re: WSJ analysis of ICE
Why on earth would any responsible politician want to keep known criminal aliens circulating in their neighborhoods?

They might not - and certainly not for dangerous criminals, rather than someone who gets clipped for a very minor offense. But again, this is the same issue I was discussing with LM in the other thread. The detainer policy has consequences for people who aren't criminals as well as criminals. Because detainer requests are not necessarily limited to people who have been convicted. So some responsible politicians object to the impact on the latter group, the consequence of deportation on the subset of people who are arrested for minor crimes, and the impact on law enforcement generally when this happens.
