What an illiterate jerk.
In the first place, there are NO Assault Rifles in the hands of "ordinary citizens". What the gun grabbers call assault rifles are only semi-auto rifles.
Second, most ordinary citizens prefer other guns for home defense. I prefer a Carbine, many prefer good pistols. The last thing I would want is an AK.
It's just plain jibberish, he is trying to justify but is showing his ignorance.
