"TSA takes any breach in security very seriously. In light of the posting of sensitive security information on the web, TSA sought to identify where the information came from. The investigation is nearing a successful conclusion and the subpoenas are no longer in effect.Since the TSA is not concerned about the contents of the notebook, I'd imagine it doesn't mind me posting the following pic of the agent's confirmation about a tweet sent from Frischling's Twitter account.
"In addition, a TSA investigator accidentally dropped a notebook, his personal property, in a public area. The notebook did not contain any sensitive security information; however, TSA will continue to review the incident."
Read it carefully, the agent tried to entice Frischling's source to come forward. So a heads up to those covering the "honeypot tweet" story.
