Regardless how stupid his statement is regarding what weapon to use, I think the video was just as stupid/wrong by putting those shotguns in hands that didn't know how to use them. Nothing wrong with a shotgun when ya know how to use it and not play with it..If the shoe doesn't fit don't wear it,, In this case,,Don't shoot it. (But yes he is clueless and without a brain.)
I have never fired a pistol grip shotgun and certainly would not do it on camera or that close to others until I became comfortable with it...
