I called bean bag as soon as I saw it. Never quite understood the rationale for nonlethal loads in shotguns....if it's worth getting out the riot gun, it's worth stuffing it with something hard.
otherwise, just tase the dude and be done with it.
Pat Nailed it--Range to target. No reason to get stuck with a knife trying to use a taser. Bean 'em at 25 yards.
