re: If we change gun control, how do we change it?

Here's the problem. And my issue with the POTUS: He doesn't wait to see what factors caused to this happening before harping on his cause. In half of these cases, there is no red flag that would prevent these guys from acquiring weapons even under the condescendingly named "common sense legislation". So given that fact, its obvious the POTUS' eye is on the prize of gun restrictions for the sake of gun restrictions, and will use whatever example he can to tug at our heart strings until he or his successors get it.

So the logical conclusion is that he either wants all guns removed from personal possession (good luck with that) or he will put something so overbearing in place such as a full mental screening for the purpose of buying a gun. Then you have that issue of the pesky 2nd amendment (the one so at the front of our forefathers minds they put it right after the freedom of speech), and you have a scenario where doctors hired by people with an agenda deciding whether you deserve your 2nd amendment right.

I don't know what the optimal answer is but I am pretty much in the middle of this and don't trust the President's intentions.
