“What message is that going to send to a DA or a jury?”
If you let a person whom you injured die by not at least calling 911 they’ll charge you with murder.
I saw a case on tv (real, not scripted) where what would have been a good shoot turned into murder because the citizen let the guy bleed out on his porch. The video camera the citizen set up to document the dead guy’s recurrent violent behavior got it all.
Anyone who causes me to fear for my life is going to get shot and very likely killed. They had better not expect me to personally initiate CPR on their carcass. That won’t happen. I will call 911 when I am able to verbally express the need for law enforcement on the scene to the dispatcher.
John Steinbeck issued a warning that all should remember:
“Don’t pick a fight with an old man. If he is too old to fight, he’ll just kill you.
Personally, I am too old to fight.
