I understand that people feel passionately about the issue but let's take a cool look at it.
In theory lax guns have an ambiguous effect, they make it easier for criminals to get guns and they increase the chance for citizens to defend themselves.
Empirically the issue is fairly clear. Countries like Singapore or Japan where firearms are illegal have less than 2% the number of gun victims than the US.
In politics the question is not "taking all the weapons away", the abolishment of the 2nd amendment, but rather how to design constitutional gun laws.
