A good number of law enforcement officials are also rightly backing another bill, which would shield some people in the country illegally but without serious criminal records from immigration holds and deportations. Brown vetoed a bill on the same issue last year, expressing fears it would block federal immigration authorities from removing dangerous criminals. This version, Assembly Bill 4, has been narrowed to address those concerns and deserves Brown’s support. Known as the Trust Act, it would allow police to hold illegal immigrants convicted of serious crimes, including some misdemeanors; those charged with a serious or violent felony when probable cause has been found; and registered sex offenders or arsonists. But it would prohibit police from holding those arrested for minor crimes – illegal street vending or traffic violations, for instance – solely for immigration purposes.
