Director: Police doctored dashcam video

Dashboard video footage released involving the traffic stop in Texas of a woman later found dead in her jail cell appears to have been doctored, an award-winning Hollywood director said.

The video showed how the incident quickly escalated into an altercation between the woman and a state trooper.

Sandra Bland, a 28-year-old black woman from the Chicago area, was pulled over on July 10 in Prairie View, Texas, for failing to signal a lane change.
