VINCENNES, Ind. (AP) – A southwest Indiana sheriff wants to buy body-worn cameras for his department's 20 deputies.

Knox County Sheriff Mike Morris tells the Vincennes Sun-Commercial (http://bit.ly/13JSvDk ) says he is working with the company that installed digital in-car cameras in department patrol cars in 2011 to get cost estimates. He hopes to then shop around for other bids.

Morris says he wants the cameras to be compatible with the cameras already in in the patrol cars. Those cameras start recording when the car starts or when a deputy flips on the lights to respond to a scene or instigate a traffic stop.

Morris says county council members appear to be receptive to the idea.

Nationally, officers in one of every six departments now patrol with on-body cameras and that number is growing.
