This is so typical of John Q Sillyvilian...anything that is OD and has a gun of any type is a tank. The M-20 is not a tank and had virtually no armor and this guy's gun is like mine set up for O2/propane. Granted, unless on a major holiday such as 4 July New Years or D Day, he should not be firing that thing so late and then only after notifying authorities. My tank used a 12 gauge shotgun with black powder blanks and my cal 50 was 02/propane, People here didn't mind...and some said it was cool for neighborhood watch. The M-20 doesn't even have tracks that one can feel or hear as it rolls down the street. Where does this fit in "stand your ground?" [:-]
