Now that I've been through the training the cops who shoot dogs and civvies for no reason seem even dumber to me.

People on twitter will say it's a training problem but no. I can assure you it is absolutely a vetting and corruption problem. Institutions larger than a medium town get bogged down worrying about micromanaging everything and don't see the forest for the trees. Then by the time a precinct gets a full roster it's a bunch of assholes who "watch out for each other"
