It's The Person

It occurs...

There are weapons and drugs in prisons.  A supposedly sealed environment has things which are banned from entering and banned from possession.

What keeps there from being more weapons and drugs out here in the "wild"?

I posit that most people simply don't want illicit items and that's why the bans on them are working.

The increasing prohibition on smoking is really only effective because the number of people smoking was actually in decline.

But banning alcohol (legally) and drugs (illegally) did nothing and has done nothing to actually stop the production, importation, sale and use of those substances.  When there's a ban on something that everyone is doing, it's simply ignored.

The banning of machineguns and shortened firearms worked, I think, because such guns were actually quite rare in 1934.  You''l note that the law didn't even attempt to ban conventional long arms.  Why?  Because those guns were quite common and there would have be a massive backlash from the voters.  Handguns were slated to be NFA items under the same law, but were pulled at the last moment when voter sentiment became known.

I have a suggestion.  Things which are common cannot effectively be banned.  What you need to do is to unass the $200, pick something off the NFA list, submit your Form 1 or 4 and help make these things more common!

Yes, there's "probulation" involved.  It's no more than you submitted to when you applied for your conceal carry permit.; your cherry is popped.

Just like open carry, we have to desensitize people at the ranges to seeing the NFA goodies.  I think we're 90% there on short barrel rifles.
