This deputy should be fired. His actions are motivated viscerally instead of cerebrally; something that training cant overcome. If he is allowed to continue he will only get better at covering his bad behavior.
Secondly, I want to express my appreciation to gigag for his approach to law enforcement. We civilians do notice and respect cops like you. A professional certainly understands and acts with dignity & with the knowledge that not everyone he encounters will possess the same capacity for logic.(yeah, I know, an understatement.

From what I have found this event happened in 2009. Seems the deputy has a reputation,as well as the county he serves; Citrus County. He is on admin leave & an investigation is being conducted. There are some questioning why this video has only recently come to light.
