Violence begets violence. Been saying that for years. If those who ar supposed to lead - authoritarian role models, if you will- are seen to engage in violence with zero repercussions, that sends out the message that it's not a matter of law, morals or ethics, it's all about who you are, if authority can get away Scott free with assaulting and killing citizens, why shouldn't I?  If you can lie with impunity, skirt and/or completely ignores the rules, why can't I do the same? Nowadays I don't see much difference between law enforcement and offenders.
