I agree with everything you said and I don't feel like our comments are in dispute- I don't think cops are killing people because we have so much murder and suicide, I think that we have a violent and gun obsessed country, and that shows itself through high levels of police violence, murder, and suicide.

Edit: as such, I would remove the "because of" part of the last sentence of my previous comment, and leave the "strongly related to". My bad.
