Airport Security and Muda

While reading on the web, I recently found this InfoGraphic about airport security practices in the US.   Many of these practices have been copies and implemented in multiple countries around the world.

The questions I have are the following:

• What assumptions would you question regarding current practices?   Which ones do you think are not valid any more?
• Are there non value added activities, or Muda involved?  Which ones would you eliminate?

How much Muda do your current processes have?
