Universal background checks, mental health screening, mandatory safety training, limits on clip/magazine sizes to name a few.
What do you think the spirit of the second amendment is and are you claiming that gun ownership is a net positive for the average citizen in terms of defense/safety?
I am concerned with gun violence generally, not mass shootings.
I'm totally fine with universal checks, as long as the cost of them is limited (and there is due process.) Ditto on mental health - there should be a *well defined* list of items that disqualify you from buying new guns, and some things that cause the confiscation of existing guns. Even a registry isn't too terribly concerning to me. I'd love mandatory training - but I'd stipulate it even be offered at the high school level, and that it be made readily available. It cannot be made into a way to limit gun ownership by requiring you take the class before owning a gun, and then never offering the class, or charging $10,000 for it (and I think those restrictions make it incredibly unlikely to happen.)
Magazine size limits...yeah, don't agree there really. The idea of making the gun take longer to reload hasn't been bearing any fruit, unless you make it so restrictive that it's impossible to use the gun (hi there, California.)
And that brings us to your question: the spirit of the 2A is the right to keep and bear arms, and the meaning of "regulated" at the time. I take the whole thing to mean average citizens were meant to be armed. They didn't say by "something less powerful than what the military has" or "muskets only", just like the 1A didn't preclude the use of microphones, speakers and amplifiers...or even TV. And I believe an armed populace not only can keep the government in check (with regards to mass internment or something) but also with regards to foreign threats.
With regards to the effect on normal people, yes - I think it's a net positive. And that stems from me believing that felon on felon (or gang) crime isn't something I'm overly concerned about with regards to the gun crime stats. If criminals want to kill each other off...well, I say give them a discount on ammo. I also discount gun suicide numbers that are always lumped in - people will kill themselves regardless of whether they have a gun (I firmly believe that both help should be there for people in a bad place, and that if someone chooses that they wish their life to end, that is their choice. I hope someone tries to talk them down, but if they have terminal cancer or something, I get it.)
There ARE statistics out there for people defending themselves using firearms, and I consider that an absolute positive (and this also comes down to my believing that if a someone's life is threatened, and they are innocent, then the aggressor's life can be forfeit.) I say this having pulled a gun out to defend myself while in my own home...I didn't need to fire the gun as I lived in an area with very fast response time from the police, but the person was clearly not in their right mind, and was beating down my door.
