Lightening up on (some) kids

There's a trial in Orlando where kids 12 and under (why's that the magical age, again?) will:

1. not have to remove their shoes, and
2. be allowed to walk through the metal detector again after it alarms instead of getting an automatic pat-down.

Are you wondering why these sensible policies are only for very small children and not for the rest of the innocent Americans flying every day? If you turn over security to a federal bureaucracy, then this is what you get: minor concessions after major transgressions.
