A lot of the seemingly useless laws trying to regulate firearm sales would work if they were at the federal level. As it is now, whenever one state or county enacts restrictions the state or county next door sees dollar signs and becomes more lenient and happily sells the stuff that's banned or regulated the town over. This argument is like socialized medicine. It works wonderfully just about everywhere else, yet American Exceptionalism keeps the naysayers going. Nowhere is ever going to be tragedy proof, but how about we make it a little harder to kill multiple people at long range with a finger pull? The idea that "oh people will find a way" and "well knives kill people too" are a viable defense for no/limited gun control is either an insult to my intelligence or an indicator of your own. Cognitive dissonance is one hell of a drug.
