Come on now. I wouldn't kid you.
Given NYC anti-gun laws, I completely agree. He would be facing prison, at a minimum, if he had even presented a firearm and the folks filiming it captured him doing so on video (assuming of course it could later be proven that it was a real firearm, and all that).
So in that exact situation, yes, he "did the right thing".
If, however, he was in a State or locality where carrying a firearm was legal I believe that he would have been within his rights to open fire.
The thing you're failing to take into consideration is that there is the propriety of the use of deadly force and the impropriety of the use of such force.
If it can be reasonably articulated that one was in fear of his life, or in fear of grave physical injury, or was in fear of the same fate befalling others, then the use of deadly force to prevent such death or serious injury is appropriate.
Once you've met that bar, it makes little difference whether you use a 5000 SUV as a deadly weapon or whether you use a firearm as a deadly weapon.
If a reasonable man can find it appropriate that Mr. RR used his vehicle as a deadly weapon I find it completely unreasonable that the same man would find it unreasonable that he use any other weapon up to and including a firearm.
I would find him to be a hero even if he used a firearm. I think most reasonable people would join me.
Two completely different situations.
Better to be tried by 12...
Again, the law makes no stipulation in so far as what can be used as a deadly weapon once it can be reasonably established that deadly force was necessary and appropriate.
For the record, I agree with you that what Mr. RR did was probably the BEST course of action.
But if he had turned to a firearm as his choice of deadly weapon I would only consider it a less than ideal choice, not an illegal choice.
Again, assuming the laws of the jurisdiction were such that legally carrying a firearm was acceptable and assuming that he had satisfied whatever licensing regulations were in force.
