I'm honestly just curious as to where you get that number of 80million Americans who don't abuse their rights?

And an ak47 assault rifle doesn't look spooky.  A Tommy gun didn't look spooky either but I'm pretty sure that the avg gun owner didn't need one.  At what point does the 2nd amendment mean arms that weren't even around when the law was created? I'm just curious about where these numbers come from sometimes.  Because unless you're babysitting your neighbors and spying on ppls homes it's pretty impossible to say that 80million people never break the law with their firearm. 1 some laws people aren't even aware of where they live and 
2 people don't usually get caught doing the things they're not supposed to do. 

Hell this applies even with fireworks. I've heard most of these talking points before however I have to wonder where these abject numbers come from when people write them down as facts.
