i'm not sure that an effective way of dealing with violence exists, once a person is beyond a certain age. you can socialize most children (or dogs, for that matter) to not be violent, calmly accept "no" as an answer, etc. but too many kids grow up with mommy and daddy telling them how "special" they are. this is the main problem with sports "stars". the entitled fucks still think they are special even as adults and that the rules do not apply to THEM, because they never have before. the death penalty does not deter them either. they'll squirm like hell & scream "it's NOT MY FAULT!" in an attempt to escape their fate, but they never once took into consideration that they WOULD be caught & have to pay the piper...
