Gov. Jerry Brown’s veto of the Trust Act late Sunday raised some interesting questions. Brown said he supported the goal of the bill, which would have set some limits on a controversial federal immigration enforcement program. But the governor said he could not support the Trust Act because of a fatal flaw that would have required police to release some immigrants who may be involved in serious crimes, such as child abuse or s, before they were taken into custody by the Department of Homeland Security. Whether Brown’s concern is valid is up for debate. Some advocates say those immigrants with serious criminal histories or facing serious charges would not be protected by the Trust Act and would remain in custody. Under the now-vetoed bill, police would have detained only those immigrants for federal officials who were convicted or accused of serious offenses; it required that all others be released.
