The woman's four-year-old daughter was inside the vehicle when the shooting took place.

"He is licensed to carry, he was trying to get out his ID and his wallet out of his pocket and he let the officer know he had a firearm and was reaching for his wallet and the officer just shot him in his arm."

The police officer is then seen approaching the vehicle and can be heard shouting into the car: "F**k. I told him not to reach for it, I told him to get his hand off it."

Reynolds responds: "You told him to get ID sir, get his driver's licence. Please officer don't tell me you did this to him. You shot four bullets into him sir. He was just getting his licence and registration sir."
