Veteran Germaine Reed was on the bus in Los Angeles when he captured some disturbing footage on his cell phone.

Reed, recently home after serving six tours of duty in Iraq and Afghanistan, recorded a Los Angeles sheriff’s deputy punching a woman with special needs. After the deputy realized that he was being recorded, he tried to intimidate him in to turning over his cell phone by threatening to search for warrants. Reed, confident in his clean record and knowing that the law officials would try to cover it up, refused to do.
