Man, 65, shoots motorcyclist in road rage incident

[sarisataka]

189. I agree, there are those

who will go where angels fear to tread, or at least somewhere they wouldn't normally go while armed.
The litmus test is would I do if armed/unarmed? The answer needs to be yes to both

In Z's case I try to keep an open mind. I do not believe it is SYG and have since day 1 said he should go to trial. IMO knowing he was armed I believe worked as you indicate. He felt a little safer and did something he might not normally do.
In the above case it is not as clear. There are too many unanswered questions... could the older man have driven off, did he get out of his vehicle, did he even lean out to vehemently return his opinion to the motorcyclist... to judge what role the gun played.

If it was a case of a sudden assault shooting could be an entirely justifiable action. If there was warning or a lead up, then there may have been overconfidence brought on by having an 'ace in the hole'
