TSA is not a government organization. Neither is Boeing nor any of the airline carriers.
TSA is absolutely a government organization, it's a part of the Department of Homeland Security. It was created by an act of Congress, the Aviation and Transportation Security Act. You might as well argue the IRS or FBI or the US Marshalls aren't a government organization. What about absolutely absurd thing to suggest.
> The Transportation Security Administration (TSA) is an agency of the United States Department of Homeland Security (DHS) that has authority over the security of transportation systems within and connecting to the United States.
