· long story short

Ken Layne is concerned that airlines may be dropping the ID check at the gate. He calls it “one of the only sane security checks—is the guy with the boarding pass the same guy who cleared the first security gate?”
John Gilmore sees it the opposite way. He points out that “People in the US have a right to travel and associate without being monitored or stopped by their government, unless they are actually suspected or convicted of a crime, and unless that suspicion is reasonable.” He also thinks the ID checks yield a false sense of security, which he thinks in dangerous.
They both make good points. Who is right?
