And what should we do?
"And what should we do?"
Don't be afraid to call a spade a spade. If they are criminals say it. If they are liars, say it. If they do evil say it. What ever happened to good old fashioned SHAME? (I know it's not PC, but PC is getting innocents killed - civility is not part of their vocabulary.)
Treat criminals like criminals. Don't let them off on a sympathy plea.
Treat bullies like bullies. Show power - it's all they understand.
Remind their followers that silence is aquiescence and they will be judged the leaders they choose and the company they seek.
