IMO.........Of course we all wish we could say targeting cops is a thing of the past, like polio. But like beating back polio, as long as human ignorance is stoked by angry mob mentality, we aren't out of the woods with this either.
I'm not sure if you remember 1968 (I'll bet Rooster does) but there are direct comparisons to the current environment: Election year, lame duck President, unpopular war, shaky economy, racial protests and street violence in large cities. It was tense times. Add radical Islamists and instant worldwide access and here we are. Wait 'til some of these ongoing police trials are adjudicated (there do seem to be alot of them), not much in the way of easing tensions likely there.
I don't know, Otis, but until we reset the entire culture of police relations, cultivate sane discourse with and among those oppressed, and clean up the broken justice system, this madness might be around for awhile. Just saying....
