Instead of treating would-be passengers as strangers when clearing them to board aircraft for security reasons, why don’t they pull up internet documentation about the person? Wasn’t this an idea not long ago? I think they referred to such documentation as “travel resumes” but don’t find what looks like this by searching on the term.
The idea should be that it is easy to do a much better job of screening people over the years, based on the other people who work with them and so forth.
If somebody has lived in the United States for 30 years, worked for the same company for 5 years, and never had any personal history that would arouse security worries, why try to do anything to figure him out on the spot?
If the same effort went into pre-screening travelers for security that goes into checking their credit worthiness when they buy a ticket, wouldn’t we be catching all the problems better than we are now?
