Fort Worth police on Wednesday defended the actions of the officers, who they have not named. Sgt. Marc Povero said in a statement that Collie failed to comply with commands to stop and that he appeared to point a silver object at the deputy, consistent with earlier reports by the robbery victim that a suspect flashed a silver handgun. Washington said Collie was not involved in the robbery. A box cutter found nearby didn't belong to Collie, Washington said.
