(FOX NEWS) A California father whose son was murdered execution-style in 2008 by an illegal immigrant gangster has launched a campaign to persuade Gov. Jerry Brown to veto a bill that would have police release illegal immigrants into the streets even when the feds want them detained.

The controversial bill, which passed the legislature in August, would compel local law enforcement in most cases to ignore requests by Immigration and Customs Enforcement to hold illegal immigrants if they could otherwise be released.

Advocates say it’s a way for police to build “trust” with local communities — the name of the bill is the TRUST Act. But opponents warn the policy could have dangerous consequences.
