The BART officer who set in motion a chain of events that ultimately led to the killing of Oscar Grant testified that Grant grabbed her arm in the minutes before BART Officer Johannes Mehserle shot him to death. According to the Chron, the testimony by Marysol Domenici came during Mehserle's preliminary hearing in which a judge will decide if there is enough evidence to order the former BART cop to stand trial for murdering Grant. Domenici said that she was trying to force Grant to sit down when he allegedly grabbed her. Her partner, Officer Tony Pirone, then rushed over, grabbed Grant, and pushed him to floor just moments before Mehserle shot Grant in the back. The only problem with Domenici's version of events is that it's not supported by the numerous videos of the incident taken by BART passengers. So the question is: Will the judge believe the videos or the cops' testimony?
