Broward County has now confirmed for me that they own the security cameras, despite telling me that they are in possession of no video taken on the date and time in question. Then they added in this gem:

“Additionally, even if they did exist, we have been informed by the TSA that this particular information (security camera recordings) is … SSI.”

Broward County has some explaining to do. Do these cameras not actually record? Do videos exist, but they are denying their existance because of their (false) belief that they constitute SSI? (SSI is a designation internal to the TSA; a third party’s records cannot be SSI.) Have the videos now been disgarded?

…and I have some research to do: If a third party destroys evidence after being notified of the necessity to preserve evidence, what is their liability?
