All 3 of them (cops & the dog owner) were in the wrong in my opinion. the dog owner was more than likely running his mouth, because there were at least 3 people videoing and he was the only one they messed with. regardless of what the dog owner was saying (unless he was threatening them) he should not have been placed in handcuffs right off the bat. bottom line is, if you'll treat the "law" with respect - most times they'll treat you with respect...
x2...I can't say for sure if the cops were in the wrong or not but...they should have given that man a chance to shut up and go home...after that if he didn't follow those instructions...then it should have been handcuffs at that time...it seems that the cops jumped the gun...
