Great article. I've worked with M for over 2 decades in various healthcare institutions. It's amazing how it has supported multi-user systems from 286's to minicomputers (remember them?) to IBM mainframes to today's servers.

I'm not sure that the average traveler/voter can judge what is good security. What seems plain to me is that there is no totally safe place on this planet and that the better alternative to hoping that TSA has caught the bad guys, is to allow everyone the inalienable right to defend themselves. Could there be a downside to this? Yes, but at least they would be responsible for their own defense and would not have been disarmed by their own government.
