>>And those are only a tiny handful of recent examples - there have been quite a few other incidents in recent days. It seems as if it's a never-ending cycle.
What if each of these cops put in a few thousand days of service before the bad outcome- and that's all some people can see.
I'm not justifying killing people and if it's deliberate then charges should be laid- but also I agree with John Wooden that "If you're not making mistakes, then you're not doing anything." The difference is that cops and others are in a position where a mistake can mean somebody's life.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
