I support ICE doing their job and deporting illegal immigrants, but local law enforcement need to be able to police without having the extra complication of dealing with the immigration issue. When there are criminals who also happen to be illegal immigrants, many of the people who will be needed by police to inform on them will also be illegal. Police need to be able to get cooperation from people to solve crimes and put bad people in prison. I'm certain ICE can find out about these criminals after they've been found guilty, since they will be listed felons. These names become public record and they should be able to find their immigration status without too much difficulty.
