LOS ANGELES ― Orange County District Attorney Tony Rackauckas, whose office faces three investigations over the use of jail informants, told a “60 Minutes” reporter that those informants probably shouldn’t be believed. Yet Rackauckas’ office has been using jailhouse snitches to help secure convictions for decades, presenting them as credible witnesses with credible evidence. The interview comes from a preview of a “60 Minutes” segment that will air Sunday on CBS about the county’s unfolding jail informant scandal, which HuffPost has been reporting on since it began to explode in 2014.
