Any attelpts to use this as another gun control argument is just absolutely obtuse. Not one gun control measure proposed would have eradicated the kind of gun likely used for this.
Gun control advocates typically are too idealistic or just stupid to understand why what they hope and dream would happen wouldnt play out in reality. They also ignore other countries that have higher gun ownership abd access yet virtually none of the gun crime we have, or the horrid alternatives psychos use where gun access is limited.
Remember, this country's first school massacre happened with dynamite ... killers use what is available.
Its a sophomoric mindset. Reasonable gun control measures to the left is an ever sliding goalpost and not really practicable.. but its a nice way to deflect the bigger social issues they dont have answers for ...
