Rebdomine also had over a hundred explosives hidden in his bedroom all of which were illegal. Eric and Dylan also illegally purchased weapons by proxy through a friend from unlicensed dealers. So yeah, the laws that would've made the Columbine shooting 'systematically harder' were already in place and they didn't work.
IMO using active shooters as an argument for gun control isn't effective. School shootings make up a tiny minority of gun deaths. The vast majority of gun murders occur in impoverished communities with cheap handguns. Nobody has any control over those weapons.
I agree with background checks and other preventative measures that actually work
Unlicensed dealers get their weapons from a source, and the source is always legal. The way circulation works is that some goods need to be put into circulation before, which means they must be created. Private companies can only produce working weapons under government supervision and require licenses. The 'source' isn't the shady dealer on the corner, but rather the gun store that the gun was originally sold from.
I personally don't believe that removing guns from the equation is a smart idea, but i also don't believe that doing absolutely nothing about regulations is the better solution either. I'd rather have a government that is actively investing in a method to prevent gun violence rather than one that will waste millions of dollars trying to completely remove and ban guns, or a government that will let gun sales and ownership go rampant with no limits.
NRA lobbying and stuff like that is probably the worst case scenario of the gun control spectrum, second being 'ban all guns from existence!'
