governments/TPTB are becoming increasingly concerned that the average citizen could get pissed off and instead of being powerless (as they have been for centuries), they may actually be capable of doing something. In this case it's criminals getting guns with nefarious intent but honestly, this is the tip of the iceberg. We are nearing the tipping point between the people being dependant on governments and companies for things like food and electricity and being self-sufficient. The prospect of "we don't need you anymore" should scare them too because it's when the current social organizational system will start breaking down. It might take a few decades but thanks to affordable automation and openly shared progress, people will start dropping off the grid in droves, not because they can but because it's easy.
