but you can't have a society where some nut shoots and kills 50 people and injures 100 ...
The problem is banning something would not have stopped this, does anyone REALLY believe that someone this demented would just throw up their hands and give up because of a law? You know what is completely illegal? murder, that ban didn't work. What about Paris in 2015, you can't say they don't have insanely restrictive firearm laws still how many people were killed by terrorists with full automotive weapons? That fiasco resulted in something like 130 deaths and over 400 injuries.
You have places with strict gun laws and places with lax gun laws, either way in a massacre situation like this neither makes a bit of difference, whether he got them legally or illegally, he was GOING TO GET THEM AND GOING TO USE THEM.
It's just a regressive opportunity to wave a virtue flag. A false solution. Something simple to blame that pushed a political agenda.
