I stand by my original reply. Why was the guy handcuffed? The answer is sketchy at best. He was told to back off and did not (HIS FAULT). The dog is his best friend and reacted like 99.9% of dogs will when they see their best friend being "attacked"
I see so many replies that say they could have used pepper spray.
Go and look at the video again. From the time the dog jumped outta the car until it is in assault mode is about 2 seconds maybe 3. Can you make that reaction in 3 seconds with a 100+ pound rotty being aggressive??
The dogs owner was a dick to begin with moving in and around the police cars with his dog. He is the one at fault here. Could the LEO's handle it better..maybe I am not sure I would have reacted any different.
