Yessir, that's a highly trained animal right there

JACKSONVILLE, Fla. — A police service dog owned by the Jacksonville Sheriff’s Office bit three individuals in a Jacksonville neighborhood, leaving all three victims with non-life-threatening injuries in the 10500 block of Forest Boulevard. 

JSO reported that the incident occurred just after 2:00 p.m. when officers responded to a report of an individual being bitten by a loose dog.

I've always maintained that dogs have no place in ordinary police patrols because they're so hard to control. This just reinforces my opinion.

If that dog broke free and just started biting random people, how much control can that handler have when the dog is excited?
