SFO doesnt actually use the TSA for passenger screening?

This TSA blog post is mostly a reaction to the story about how airports can opt out of hiring the TSA for passenger screening, reminding people that even if an airport does this it’s still regulated by the TSA — they still have to follow the same procedures the TSA would.

However, it also comes with a list of airports where security isn’t run by the TSA. Of personal interest, it includes SFO. I guess I’d noticed different uniforms on the security personnel but it hadn’t registered that they weren’t actually TSA.
