We're speculating. Again, he could have had a gun and the same thing could have occurred. If things escalated even more he could have then used his weapon.
It is easy to say what the right choice is now that the incident is over.
I really don't care enough about it to have a pointless tit-for-tat internet argument over it, you're pro-guns, I get it.
The point is we aren't speculating. The kid didn't have the nerve to shoot someone over a camera fortunately but he probably would have if they tried to pull a gun in defence. Things couldn't have escalated any more than the existing situation of having a gun in your face. The next step up is getting shot, which would probably happen if you try and draw your weapon when someone already has a gun at your head. I'm not saying guns can't be used for self defence, they obviously can, but this is an example where as chance would have it the situation would have ended worse, or at best the gun would have been useless anyway.
That's my position, if you don't agree that's fine.
