Oh shut your ranting pipe hole - calling people names who simply disagree with your long winded crap. Give it a rest, it must wear you out spouting so hard.
The dog is dangerous. You don't unarrest someone to deal with a dangerous dog. Not sure what world you live in, but it's a lovely fantasy!
Too many Neowinians with bleeding hearts here ignore that:
The guy was looking to mess with the police, he said it himself in interviews.
He surrendered himself without explanation.
He hadn't been searched yet.
He could have pulled a gun from his car. Therefore, no effing way they would uncuff until he was searched. The dog jumped out before that happened.
It was a crime scene, and no, passerbys are not allowed to potentially interfere. We don't know the whole story and he may have been a potential suspect for loitering, loud music, and (whether people agree or not) had what is considered a dangerous dog on a leash, a little dog leash that the dog could have broken free from anyway.
The dog lunged to bite the officer, it was not without provocation. The dog could have had diseases.
The owner knowingly left his windows down, which would allow the dog to jump out. If he didn't know that, he is an idiot and just as much at fault as the officer who pulled the trigger.
