As a father, I became very emotional reading your essay.

However, I think this type of emotion can also colored our interpretation of "guns" in America to the point where your argument is a failure in logic.

The 2nd Amendment was discussed more than any other by our Founders.  For good reason.  It's not there simply for "personal protection".  We have a 2nd amendment for the original purpose of overthrowing a tyrannical government.  There are a plethora of contemporary political examples.

The majority of gun deaths are SUICIDES.  And you failed to mention all the times that guns PROTECTED a family or saved a life.  

 “If you are for gun control, then you are not against guns, because the guns will be needed to disarm people. ... There is no such thing as gun control. There is only centralizing gun ownership in the hands of a small political elite and their minions.﻿”.

There is no law, no rule of man, no barrier that would have prevented your daughters attack.  

God bless.
