Keep in mind that cutting off a shotgun barrel 1/2” too short is a felony, as are many drug offenses.
The focus should also be on making fewer crimes felonies to start with. But this is a good start.
If you cut a shotgun barrel, or if you don’t, be sure to document it.
The government had people who will take an 18 inch barrel down to 15 inches, and then claim that you sold it to them that way.
Just like they have police officers who will find drugs in your car, after they put them there.
Too darned many things are illegal, and police are pushed to get their quota of convictions. Some are not ethical enough to resist the pressure.
