If my son were being beaten to death and called to me to help him and I was not there, my soul would be so tortured forever after that I would have no concern for the consequences of any action I took in retribution. I wouldn't give a sht about some academic BS argument that it was "legal." it was a heinous, inhumane, torturous killing of a frightened, weak man with the mind of a child. It needs to be made right.
Forget the legality. Forget the politics. Some things are right and some things are wrong. This was wrong.
