Maybe they should be issued some harsh language as well.
Sling Shots can be very deadly. They are silent, do not produce a muzzle flash, can be concealed w/o much problem, and there is an unlimited amount of ammunition.
I had a wrist sling shot as a kid and could kill a rabbit at 30 yards with just one of my store bought marbles. Gave it up when my dad bought me a .22 with a 20 round clip. Guns were just so much cooler.
