Well, some of you have met me in person at games, I come with my son, and use a FAL. Yes, I am an expert, if you show up at Hatfield, I'll be happy to give you my card.
As I noted, there are frequent instances where the law over-reaches. If you are so persnickity, you'd best sell any gas-guns you have. Under Arizona law, any gun device that operates off of "expanding gas" to expel a projectile, is a "firearm", and if you shoot another person with it, you can be charged with "aggravated assault, a dangerous offense". This carries a minimum sentence of 5 years in prison. Better quit playing paintball too, just to be safe. Under Arizona statutes getting an abortion is illegal as well, with a sentencing range from 1 to 5 years. Also, don't glue two toothpicks together connected by a piece of dental floss. Under Arizona statutes, that would qualify as "nunchuks", and would be a prohibited weapon in the same class as a machine gun or rocket launcher.
My point is that just because you looked up a "rule" doesn't mean you understand it the way it is used in the real world. The law is much more undefined than most people realize. Since people facing the death penalty trust my advice and judgement, perhaps you shouldn't be so hasty to rather rely on your "internet search". I'm offering to help out here, free. If you'd rather roll over and submit to any show of authority, then I take it you haven't read your history books.
