A gang unit officer in Albuquerque, N.M, has drawn harsh criticism from the city's police chief for listing his occupation on his Facebook page as "human waste disposal" after his involvement in a shooting last week.

Albuquerque Police Chief Ray Schultz said he felt disgusted about the officer's posting on the social networking website.

Detective Trey Economidy's post has since been removed from Facebook.

"Obviously I'm very disappointed in the comments themselves and the nature of the comments," the chief told The Albuquerque Journal. "Honestly, I went from disappointed to disgusted. This puts the department in a very bad light."

"That said, I know Detective Economidy, and this is not the type of person he is," he added. "He wants to make a difference. But he clearly had a lapse in judgment here."

Law enforcement agencies across the country have been struggling with how to handle employee comments on social networking sites such as Facebook and Twitter, Schultz said.

Authorities have launched an internal affairs investigation after a fatal shooting last week involving the gang unit officer. It was the first officer-involved shooting this year for the APD.
