Galveston, Texas - Officer Blake Patton puts his right hand on the butt of his gun and shouts, "Anybody there?"
The house he has been ordered to check looks deserted, but you never know. Patton and his partner, Mustafa, disappear around the back of the house, and a gunshot is soon heard.
A pitbull that was locked up in the backyard is killed in the operation.
"He charged against me, and I had no other option," Patton tells Deutsche Presse-Agentur dpa as he wipes the sweat off his forehead.
His boss is not happy.
