If you took the time to watch the video or actually had a brain (either one, you pick if you're capable) you would know that the cabbie never would have had a chance to use it and probably would have been a victim of his own gun as well.

Add to that the concept of cabbies carrying guns in that environment plus the attacker being shot dead for that offense and the sum total of that equation is ...... you're an idiot.

A partition and lockable front doors would have protected him in this case. Too bad he didn't have those options.
