Anecdotally, it is. The rates have increased. Of course, as measures are taken to restrict firearm ownership, a black market will exist. We're starting to see that. These things are being printed, and 3D printers are also becoming a lot more common across North America.
It's one of those things where you're going to start needing to target the demand side of the equation. You're trying to control the supply side right now by banning firearms based on spurious definitions. Really, if you don't start targeting the demand side, you're not going to see any benefit.
You're usually targeting legal gun owners who are going to comply with the regulations. They are the least most likely to be involved in criminal activity in this country. They have already gone through screening. It's no wonder that, when I look at this legislation, I don't see any benefit, because you wouldn't expect to get any marginal benefit on a group that is already such a low risk.
That's probably where you should start directing your work. It should be towards the demand side.
