I've repeatedly gotten airport CCTV, both from TSA checkpoints and other areas (e.g. arrival waiting area). I always ask for it under both state (airport) & federal (TSA) FOI laws.

For all the other BS they've claimed, TSA itself has never claimed to me that CCTV is FOIA exempt or SSI. However, they do always take a year or two to process a request.

State authorities (i.e airports), except BOS, are usually much faster to respond and generally have less BS (except states with a citizenship requirement, like TN - but muckrock.com helps with that). They also are the ones that hold the footage to begin with, so they have to get the request to make sure it's kept before the 30 day standard retention period expires.

BOS did try to claim that it's SSI (TSA didn't back them up on that), and exempt under §(n) of the MA PRA because the location of the cameras is somehow secret.

Nevertheless, I am in possession of CCTV from two separate events at BOS, thanks to the combination of BOS agreeing to preserve it and TSA having to hand it over. (On the other hand, they also failed to preserve all of it both times — both times omitting some crucial parts.)
