Earlier quoted context omitted.
We know what is different but we refuse to address it. I understand that many people feel the second amendment is very important, but we at least have to have the intellectual honesty to admit that shootings like this are a consequence of it. We might decide we are willing, as a society, to accept that risk, but we can’t pretend it isn’t there.
I don't see much of a plausible argument that lack of gun control makes American police more trigger happy. And I say that as someone with no particular stake in gun rights. America doesn't have that high a murder rate, it just has a high rate of killings by cops. Lack of training, poor training and overall problematic police-culture seem to be the main offenders.
That said, I'm a believer in the second amendment -- I just think there's definitely an argument to be had.
