Doesn't matter if it is true or not, it is not your life, your choices, and it is not up to you to judge another human being on how right or wrong they are.
To comment on "Your hero" who is first a human being, then an actor, and then a teacher of Aikido is neither your place or relevant in any place than the gossiping 'old lady" gossip phone conversation.
Let it go.
Real life is not the movies, and the movies are not always real life.
If you ever have to deal with a psycho who is convinced that the other side of lawful society is where the truth dwells, you would know enough to define where discression is the better part of valor and where getting physically involved means you have to kill not only the offender but his friends, family and associates that may be offended by his/her death.
The meek may inherit the earth, but the smart live long enough to dance on the graves of their enemys.
Yeah, I am a dancing fool!
Crank up 'da music Vinny!
