it is a Bad business , they don't care how many people are killed or will be killed, maimed ...the interest of their Good business came to a point when they wanted to black mail any country , ohhhh! the cry , calling to stop killing of innocent people, children or women......but many countries are using their Guns to do the business of killing people.
the case with criminals , would be minimal for no one is allowed to own guns. take for instance Germany. TBT
