TSA is confiscating stuff and either selling it off or giving it to others to sell off. That's theft.

Bringing a prohibited item into a secure area, especially when it is posted that the item is prohibited, and having it taken from you is not theft. BTW...the definition of theft has nothing to do with the final disposition of the item...but other than that, you were right on.
