“...Bet he wishes he’d had one of those ‘icky assault weapons’ with a ‘high capacity magazine’ that ‘civilians don’t need.’...”
That crap right there is one of the biggest advertisements for the 2nd Amendment ever made. As you so aptly stated, It’s also denounces hi-cap mag ban arguments as well.
Any doubts I ever had about civilians needing a fast-firing semi-auto with large magazine capacity ended in Los Angeles in 1992. Sadly, too many idiots did not reach the same conclusion.
