Here's mine:
It is important to not under emphasize the tragedy that happened January 8th., and it is also important to realise that a restriction on common, standard capacity magazines is a bad idea.
First you are restricting the ability of the law abiding person to defend themselves when faced against a group of criminals or one criminal who already has these magazine. (Take for example the person in New York City who had 24 people harrasing him at the front of his house. Even if they were limited to just ten rounds in their magazine, that's 240 shots against his 30 at best.)
Second, these common capacity magazine have been out for many years and will still be out there if they do limit future ammunition magazines. All they will do is create the environment for the rapid buying of nonrestriced magazines until the change over happens and a large market for these magazines ,either legally of illegally, after it happens.
Instead of focusing on what was used to kill and wound these great people, let's figure out how to stop these people from killing in the first place. Take away the reason and the how will fall away by itself.
I wanted to put the focus back on the person, where it belongs, and not the gun. That's why I have that last paragraph.
