Good luck with that one. I doubt if one-percent of gun owners would comply. I would add that you would have to convince the public to accept some form of national ID card, to make this even marginally work. But maybe you could attach this to the same national ID database for voter registration. (spoken sarcastically of course)
I sure as hell wouldn’t comply. And I’m old enough my attitude is I’m going to die free man one way or the other. Molon labe.
How many of those bastards come with me is going to be their decision. I will take long as many as would like to come.
