Trump has nothing to do with it, neither does the NRA. The only question should be why more people are now going bat s*** crazy than in the past. Clinton's assault rifle ban did zero in the 90s. Chicago has some of the toughest firearm laws in the country, again, zero positive results. The huge majority of legal weapon owners commit zero crime, those licensed to carry concealed even less. It's society and the downward mental spiral of the few. There is nothing that can be done to stop crazy from killing.
