One thing I was thinking today: Our side always uses the argument that suppressors are rarely used in crimes. That is true, in no small part because of how few there are in circulation. Yes, I know, anyone with a lathe... But your average criminal is too lazy to learn to use a lathe, and the ones who are willing, are the reason it is 'rarely,' not 'never.'
Once cans are deregulated, and can be bought as easily as a handgun, criminals will start to use them. And then we can go through the media circus again.
