"No way"? Really? Just impossible? We've already put limits on the manufacture and distribution of firearms. We can certainly put limits on mag capacity. Would that stop 100% of illegal usage? No, but then speed limits don't stop speeders. So, why have speed limits?
As for examples, see PRIOR RESTRAINT. Give out classified info and see what happens.
Let's keep this on point. Is the justification for prior restraint because there's no "need" for people to give out the information, or is it deemed to have caused some harm, which is an objective purpose for the law? Because that's kinda what I asked for. Because you continue to insistence that "need" is a determinant for restricting rights. I asked for examples of *subjective* reasons to restrict other rights the way you want to apply subjective reasons to restrict the 2A. So let's try this again.
"just that an AR (in its current design) is not appropriate for most applications"
Find examples where restrictions on rights are as subjective as that.
David's opinion that the AR is not appropriate for most applications is not an acceptable reason to restrict rights. I am a little biased, but Jamil's opinion that AR-15s are an excellent platform for home defense, varmint control and other hunting, and well as for competition shooting, supersedes david890s opinion that they aren't appropriate. And plus, I beat you tens of millions to a few hundred in empirical data. Millions and millions of citizens seem to find them appropriate for many legitimate uses compared to the few hundred that find illegitimate uses.
