CBS said today it is moving the struggling Brooklyn D.A. to Saturdays at 9 PM beginning June 22. Saturday will be the final burnoff spot for the show. Since its low debut on May 28 the six-part docu-series about the NYC borough has tanked in the ratings on Tuesday nights. Brooklyn D.A.was down 23% from the premiere last year of docu-series Dogs In The City on May 30, 2012. The show fell 20% in its second week and was down 14% to a 0.6/2 this week from that June 5 show.
