The cop will walk.
Given the lack of video, it seems likely the cop will walk....
“A Dallas police officer involved in the shooting of a mentally ill man, that was caught on camera, has been fired. Surveillance video shows Cardan Spencer was 20 feet away from paranoid schizophrenic Bobby Bennet when he shot him in the stomach. The police officer and his partner had maintained their story: that they were forced to shoot after the man threatened their safety by lunging at the pair with a knife. Officer Spencer has now been fired pending a criminal investigation after a neighbor released surveillance video capturing the incident that showed nothing documented in the police report actually happened.”

If you are dealing with cops, having video to show what REALLY happened is critical. Pity, because it didn’t used to be that way.
