I cannot believe that the TSA would ever release film of a non-criminal incident.
While I believe the mother was wrong in more ways than one, incidents such as this should remain confidential.
Cleaning it up, well, that is kinda pushing it.
Personally, I think they should have notified the airline's GSC and let them make the call to let her fly.
Only one person has an excuse to act like an infant in this instance.
JMHO though, I wasn't there.
