None of those things are detrimental to the safety of others. We've installed regulations on amendments for safety reasons before.
Sorry but it's NOT your constitutional right to own a killing machine. And even if it was, that right can be regulated for public safety.
I don't mean to get semantic if it's not what you meant, but what do you think an "arm" is?
Where we differ is that I don't think (and based on voting, a majority right now don't think, though as you assert that may change) that doing more regulation of a law-abiding citizen makes it safer. I submit that people aren't safer in theaters now because you've infringed on the law-abiding citizen's right to yell "Fire!", they're safer because we've made it so you can't smoke inside them, they have to have multiple exits, you have to have adequate walkway sizes, max capacity codes, etc.
As just a puerile example, the current laws in FL ban guns from schools at all hours. Yet a criminal brought a gun to school. And violated the law against murder.
I'm all for constitutional regulations, but as I wrote above (that hasn't been commented on yet), registries have been shown to be abused by those in power. Even "background checks" without due process have removed Constitutional rights from people. I think we already have a lot of laws on the books about gun ownership and use, to the point that I couldn't purchase one. Yet somehow people get killed in BAL, CHI, Parkland, Chattanooga, Navy Yard, Fort Hood, etc. when bad people violate laws that good people have to live by. As stated above, I can live with that (or leave the country) for things like driving, health care, abortion, etc. I don't have to live with it for Free Speech, Freedom of Religion, Keeping and Bearing Arms, Voting, Self-Incrimination, etc.
