Hundreds of metro Atlanta police officers are putting their careers on the line because of what they are posting online.

Ken Vance, Director of the Georgia Peace Officers Standards and Training Council (POST), tells Channel 2 Action News cases are piling up involving officers who posting inappropriate pictures and messages, putting their career and the agency's credibility on the line.

Vance says the cases have skyrocketed over the past five years.

"I used to say there wouldn't be many things that would make my jaw drop,” said Vance, “one of these pictures made my draw drop."

In a case in west Georgia, Vance says an officer who left one job for another posted an inappropriate picture on his Facebook page.

"Posed on top of a police car, urinating on the police car,” said Vance. “What I was told is this officer had a very promising career -- not anymore.”

That officer was suspended and applied to be reinstated in two years.

In Clarkston, two officers in uniform were posing with a partially-clothed adult actress leaning in the patrol car.  The picture was found on an inmate's phone.

Vance says they've investigated 200 Internet-related cases in the past two years.  He said some of the officers told him they took the pictures because they were drunk of they didn’t think anyone would ever see them

"I said, ‘do you not understand that this goes everywhere,’” said Vance.

Defense attorneys in other cities have used the controversial web postings by officer to bolster their cases.  In some instances, charges against the criminal were dismissed because credibility was compromised.

The Georgia Association of Chiefs of Police has drafted a social media policy that seeks to balance the free speech rights of officers and protect the reputation of police agencies and law enforcement.
