The Alameda County Board of Supervisors unanimously approved a proposal for “ICE-free zones” at yesterday’s board meeting. Now, no property owned or controlled by Alameda County can be used for ICE activity. Next, the county has to identify the properties it controls and train security guards on how to prevent ICE agents from entering without judicial warrants. Six Alameda County residents were arrested by ICE last year, according to Public Defender Brendon Woods. Sheriff Yesenia Sanchez clarified that her department can’t prevent ICE arrests in public areas on county property.
