The Youth Accountability Team (YAT) program was created in 2001 in Riverside County to target at-risk youths for intervention. But YAT treats children who have not been convicted of crimes like hardened criminals with surprise searches, unannounced home visitations, strict restrictions on who participants can speak to, curfews, and interrogations into intimate details of their lives. It's a program far more likely to be applied to youths of color.
