As former BART cop Johannes Mehserle is expected to be arraigned today, the Chron reports that District Attorney Tom Orloff has seen additional video footage of the shooting, which he calls "very helpful" and seems to have been key in his decision to charge Mehserle with intentionally killing Oscar Grant. Meanwhile, in Napa, members of Mehserle's immediate family found two suspicious packages outside their home. Since Mehserle's been getting death threats, the family called the cops, who blew up the packages. No explosives were found inside.
