The federal immigration enforcement program supported by Sheriff Lee Baca and used in county jails has faced growing local opposition in the past two years. Now Se Communities is facing scrutiny from the feds themselves. Two recent internal reports question whether the Department failed to communicate early on whether states and counties had any choice in joining Se Communities. Another addresses whether the enforcement program has been effective. The reports were a response to Congresswoman Zoe Lofgren from San Jose, a critic of the program. The way Se Communities works is simple: when a person is booked into county jail, the detainee’s fingerprint information is shared with immigration authorities. If the person is in the country illegally, deportation proceedings could begin immediately.
