... Is it so hard for people to believe that cops would do this? Maybe you guys have nicer cops than Colorado or something (which would blow my mind as our everything is generally friendlier than other states according to my experiences) and I have no problem imagine them doing this.
Cops, rather regularly, kill people and injure people (at the very least once a day I'd imagine). My theory is this sevearly damages their emotional connection to the citizens, as well as their concept of of how serious it is to hurt someone else.
If I ever broke someone's bone, or honestly just injured them in any way I'd feel terribly upset about it because it NEVER happens. By contrast think of any time you have seen cops hurting someone, usually they don't react at all, it's just a part of the job, like taking out the trash or locking up a store if you work retail.
It's just something you do every day, and so every day it means a little less to you, and when violence becomes internally inconsequential you really open a whole new terrifying world of possibilities.
One way or another, everyone should be careful out there because I'm observing a growing Us vs. Them mentality between the cops and lower class citizens, and they always seem to be looking for an excuse to get violent to show us our place in the modern caste.
