The moral of this story is to not be wrang and strang and maybe some madman won't shoot you in your head for said wrang and strang behavior.
Where is it reported that the victims were wrong and strong?
It seems from numerous news reports that the victims were parking in his spot despite numerous complaints over lengthy periods of time to them personally and to their property manager from the murderer.
Look, no one is saying one should get shot in the head for being an ass. I just think it's disingenuous when we all pretend that we don't understand that this dude was dealing with some jackasses who happened to be Muslims and he lost it one day when they finally parked in his spot one time too many.
I wouldn't shoot a person in the head over a parking spot, but I live in NYC...I understand his frustration.
