The BART board of directors has picked an outside law firm to investigate former officer Johannes Mehserle’s fatal New Years shooting of Oscar Grant, and the winner is… Oakland’s own Meyers Nave! So step on up, fancy lawyers, and do your thing. Leading the probe will be Jayne Williams, who used to run Oakland’s lawsuits as city attorney. In addition, the Trib reports, BART has asked Reginald Lyles to help it set up a civilian police review board; Lyles has worked with Berkeley and Novato when they were dealing with similar issues. With cop killing, a little more progress is made, it seems.
