I know you can do better.
Guns are used to commit crimes, and people have a right to defend themselves and to bear arms, society has determined that the proper balance is to run background checks on people buying guns and to do some other things, things that are generally ineffective but that's not important. Different groups keep pushing the balance around, and if all of a sudden guns were no longer being used by criminals then those wanting less gun control would probably make great strides.
Today suppressors are rarely used by criminals. Frankly I don't think criminals are very smart, but they also have to deal with concealment and presentation, both of which suffer when a suppressor is bolted on. This may also be in part because the increase in the number of suppressor-ready guns is a recent event, It doesn't really matter, what matter is that they aren't used in crimes today and so there is a reasonable argument that freedom has been diminished based on unfounded fears and that we should correct this injustice.
Sounds great, take suppressors off the NFA, and everyone reading this buys a few more, man it would be great.
Now I theorize that in a few years criminals will commonly be using suppressors. You and I know that they probably aren't going to be doing anything new, they are committing the same crimes, but maybe there is an increase in crime and a reduction in successful prosecutions. If that happens then the left will push harder for additional gun control, and we might end up with suppressors but with full registration, or me might lose suppressors and be required to sell only through FFls. We sure as hell won't be making progress on getting anything else off NFA.
So my thinking is about how to take a step forward and be positioned to take another step forward while reducing the risk that we take two steps backwards in a few years. My first idea was keeping the cost high, but registration is another option as is harsher sentencing guidelines. It's a straw man, take a poke at it if you like.
