This is sort of close to where I live, I'd say 40 miles maybe. I never go through Aurora, but something like this can happen anywhere in any city. I can foresee some MAJOR changes happening across the country because of this. The anti-gun lobbyists of course will be all over this but other issues as well.
Just as Tennessee recently has been a beta-test for using TSA on Tennessee highways working jointly with the Tennessee highway patrol, it wouldn't surprise me to see TSA now start spreading out slowly but steadily to public places of business. Tightening security in shopping malls, auditoriums, civic centers , movie theaters,ect. with armed security and metal detectors, ect. I don't think we are yet at the point to where we have to go through metal detectors to go see a movie but with these type of events increasing I can see that day coming near.
