Shooter incident at elementary school in Uvalde, Texas - 19 children and 2 adults dead

I think you’re description is over broad- ‘society’ didn’t shape the police so much as landed gentry and slave owners did
One ‘fix’ would be for the police to be reflective of an actual democratic society and have civilian review as an integral part of policing
I’m just throwing a blanket out there. Sure, “all” society isn’t to blame, but a significant portion is. We have had a few years since the last slave owner to steer ourselves in the right direction and haven’t. It’s going to take all of us to right the ship. My point is that sitting on the porch hollering across the road and shaking your fist isn’t going to solve anything. As much as a lot of us like to think “I’m good, they are bad”, no one is good all the time or as good as they think they are.
