As any security expert knows, a chaotic checkpoint is a security problem. "If terrorists can anticipate that, it gives them an opportunity" to try to evade various layers of security by creating an incident for diversion, Mr. Pistole said. "And what would this do for travel plans for Thanksgiving? Are people going to miss flights because there are long backups, because other people are protesting?"

This just sounds like fear-mongering. Even if people miss their flights, it's the TSA that should be blamed not the protesters.
