The officer was convicted of assault earlier this year for the incident from last summer. The appeals court agreed with the police that the officer felt threaten by the man and was working alone when she confronted him.
The film, recorded by an eyewitness, shows the officer and the man talking out on the street. He appears to be drunk and talks about "blowing the whole street up", but he is calm and physically passive.
Suddenly, the police officer raises her voice, ordering the man to lie down. She grabs her truncheon and releases her dog.
The man moves down the street while trying to make the dog stop attacking him, calling "tell him to stop biting me". At the same time, the police officer beats the man repeatedly until he finally lies down.
