I have no sympathy for cop killers, but I do pray for the man's widow, and the officer's family. The pain he has caused I'm sure is hard to bear for all of them.
The irrational ideologues are not so numerous, just endowed with big mouths.
I can only comment upon my experiences, that some people will try to shoehorn the facts into their perceptions, whether the facts fit or not. We all do that to some extent. But most of us know when the facts ain't gonna fit, no matter how hard we try, and we don't bother with further effort, but instead alter our perceptions to fit the facts...
Why, indeed?
