A story from the July 3, 2011 Seattle Times about a new improved crackdown.  Its about Washington State, but the story addresses issues we've been interested in.

Significantly:

Secure Communities has come under fire from immigrant-rights groups, which worry that the program will cost counties money, lead to racial profiling and disrupt immigrant community trust in law enforcement. Some fear the potential of deportation could hinder reports of domestic violence and other crimes.

In November, Washington turned down ICE's request to implement Secure Communities throughout the state, instead allowing the sheriff of each county to decide if their community wanted the program. Until Yakima activated the program last week, Washington was one of only six states in the country that was not using Secure Communities. ...

Currently, ICE gives counties the option of participating in the program, but every county jail in the nation will be required to implement the program by 2013.
