Because the vast majority of these shootings are done by giant ******* and wimps and cowards who couldn't and wouldn't have the balls to be so up close and personal.
Not kidding Luther. The same thing can be said for gang violence. These so called tough guys and hard arses shoot each other like it was nothing, but, what if you had to settle your "beef" by a good old fashion Indian knife fight? How many tough guys would there be willing to tie up and go at it with the knives while tied together? I can say very, very few.
