Sammy's Law defeated

Assembly bill 1828, aka Sammy's Law, was to require Child Protective Services in California to record its interviews. These interviews are used as evidence to take away children. Law enforcement must record their interrogations, but CPS does not have to. When deciding whether to take a child, the court relies on CPS' testimony, not police reports. A committee killed this bill under pressure from the social workers' union, without a vote. The money issue was one objection. Hey, almost everyone has at least a tape recorder. Why not just bring one from home? Or why not at least allow the interviewees the option of taping it themselves? Since these interviews are used to prove child abuse, I don't know why they aren't required to be better documented.
