When I lived in South Bend the cops got an alarm from a warehouse. Being intelligent folks, they send a dog in through the broken door first. The burglar was promptly corned by the dog, who barked and growled to keep the guy in place (as the dog was trained to do). Then as the handler rounded the corner he saw the crook kick at the dog, which dodged the kick and clamped his teeth onto the baddy's leg -- drew some blood, too! The baddy kicked with his OTHER foot and of course fell to the floor. Now the dog tried to drag the crook to his handler, who was right there and put handcuffs on the burglar and called an ambulance.

The guy was eventually sentenced to ten to fifteen years (he had quite a record) and the dog was decorated.

However...the guy sued the city because the dog bit him and caused him to fall to the floor.

The court had a good laugh as the suit was dismissed, with prejudice. Oh, yes -- the entire sequence was captured on the warehouse security cameras!
