What makes you think that? It hasn't worked for gun control, and plenty of people (most certainly including a lot of gun owners) feel just as strongly on this issue. This was a big thing in the '90s (along with Federal level gun control), it all failed (like the worst of that Federal level gun control), and eventually the government stopped controlling encryption as a munition. What's different this time, besides the currently not very hot in the US GWoT?
