If after so many incidents and warnings the owner still cannot be responsible for her dog then maybe she should be the one who is put down :P

"Neighbors said they didn't feel safe approaching the house." But they feel plenty safe calling the police and mouthing off to the press. Is that you Boo Radley?

Don't the police have something better to do? We have murders, young ladies being kidnapped, and home invasions going on all here in Mountain View recently!

I bet the "neighbors" will feel so much better, when they scare off this dog owner, and have the house occupants replaced by a gang members and drive bys.

Let's be real. Animal ownership requires being responsible for that animal. This dog has shown that he can be aggressive and dangerous. I can see why the police are involved. They should be. The owners of Sylas are negligent. It isn't the dogs fault. He is just doing what unaltered male dogs do, protecting his territory. His owners should be keeping him home and under their control at all times. That is the law!
God help the owners if this dog hurts someones child. If they own their home they might not want to loose it in a lawsuit because of their dog. It's called liability.

This is a public safety issue, therefore the police are involved. Dealing with complaints of a dangerous animal is the police department's duty, just as it is preventing and responding to other crimes. Because there is a threat to bodily safety, I'm sure they put this higher in priority over certain duties not directly related to safety but lower in priority than murders and kidnappings.
