It's because innocent people are starting to object to the treatment, and cops see the objections as "resistance" (their training and steroids tell them so). Cops hate "resistance," so they take it as a license to beat the living carp out of anybody they like, better still if they are killed in the process because dead people cannot sue.
Cops are also trained to see dogs as a threat, so they are simply shooting them on sight. They also see video-cams as a threat, and have tried on numerous occasions to confiscate them, and even destroy them. Not being the brightest creatures on the planet, the videos often survive the attempts to destroy them.
I guess this would be a great way to get rid of that pesky neighbor, if you were dishonest and had no conscience.
"Swatting is the tricking of any emergency service (via such as a 9-1-1 dispatcher) into dispatching an emergency response based on the false report of an on-going critical incident." Wiki Link
One could also claim that their neighbor is involved in suspected drug activity.
