You can't, you can never completely trust people. A few years ago there was an incident where an Egyptian airline pilot suddenly screamed "Allahwakbar!" and put the plane in a nose dive. Everybody died.
But that's not the point. The point is, there will never be complete safety. It's physically impossible. However, that answer is considered heretical. And while we're at it: the security measures at the airports do exactly nothing to make us any safer either. They're not even designed to do that. They are designed to impress politicians. All that gestapo compliance crap is just a nasty side effect.
As far as this guy is concerned, it's just another variant of "rage quit", because he essentially did this to quit his job. There is no way in hell he didn't know exactly what would happen. After years and years of going through all the motions of Security Theater he chose to do all the things that get you red-flagged. His point was of course to demonstrate that we don't live in a free society anymore. But we knew that for some time now.
