Do you think driving is a privilege?Depends upon what I'm driving and where and whether I'm intoxicated or not and so forth.
Hell FREE SPEECH is a privilege - there are libel laws.No. Free speech is a right. But, because it is a right, does NOT mean that anything you say cannot be actionable under law.
Just as gun ownership is a right, but that doesn't mean you can shoot anyone you want to.
Traceable ammunition is clearly in the public interest.You keep claiming this DESPITE it being shown how the criminals would quickly avoid any links to themselves AND being shown how it would turn currently legal activities into illegal activities.
Again, we SHOULD have learned this lesson from Prohibition.
It doesn't say regulation of dangerous things cannot be done in the public interest, to the extent the "several states" deem necessary.Just as we outlawed the dangerous substance of demon rum.
And firmly established the Mafia.
Because it is LEGAL to pass some laws does NOT make such laws INTELLIGENT nor EFFECTIVE.
