My Google-Fu is failing me, I can't seem to find the right search terms. Or Google doesn't want to give up the info I seek. How many people in America are prohibited by ATF rules from owning firearms? Not how many denials are there, I mean people who wouldn't pass the background check if they tried, but buy guns illegally. A different but related question, how many armed thugs are walking around in this country? That's a question impossible to answer, but maybe someone has estimated it. I figure with a high recidivism rate, violent felons that are out of prison would comprise the vast majority of this number. The big picture I'm looking for is, let's say there's a pie chart. One part is "armed law-abiding citizens." That includes CCW holders (estimated at 5% of the adult population) and just general law-abiding good guys who happen to own guns. One part is law-abiding citizens who don't own guns. One part is "bad guys with guns (or knives, etc.)." There are other groups of course, like bad guys without guns, but for my purposes I'm not interested in that. Those can be a "miscellaneous" wedge of the pie chart. I'd like to know the relative proportions of each. It would be useful when discussing how many people are affected by poorly-conceived gun laws vs. how many people will always ignore gun laws. If the good guys outnumber the bad guys by a significant margin, then we can legitimately prove that gun laws are hopelessly and dangerously misdirected. Not that legitimate proof will ever sway an anti-gun fanatic, but at least we'll rest easy knowing the truth. If good guys with guns are outnumbered by bad guys with guns, then we're flirting with chaos.
