You need to read further. There are a few FReepers who believe that cops can do no wrong, but I suggest you look up Jose Guerena or Kelly Thomas in the keywords. A majority is totally against the misuse of police power.
This dog-killing is another facet of the police state which is slowly being imposed. Most of us are outraged by every aspect of the current situation.
Psychopaths begin their careers of murder by torturing and killig pets. I suggest to you, that police officers being trained to murder pets is a stepping stone to killing humans.
I don’t separate the progression. The activity of cops raiding homes of innocents to capture the guilty is an example. There is no reason they don’t capture the guilty away from the home of the innocent. Unless they are inure to killin’ which is the whole point of their training to kill.
