You realize of course that the backlash from this isn’t going to result in anything intelligent and effective. We’re just going to have a new rash of 6 year olds getting tackled by the swat team for making a finger gun and yelling “bang”, and introvert teenagers getting treated like potential war criminals over their comics and video games. Laws will be passed restricting cosmetic features of certain types of guns (maybe), and people will continue to believe that an absence of clinical mental illness (e.g. schizophrenia) will mean that external rather than internal causes must be assumed. We (over)react to danger with hysteria, which is why we have a gun culture in the first place.
