That’s basically the system we have in Australia - customs and immigration handled by officers of the Federal Government, and generally Federal police patrol airports (one of the only places you will normally see them if you don’t live in Canberra), and then the airports have private security companies do the security screening.

There are still Federal standards they have to comply with but it’s more reasonable than the US (we never had to take off our shoes and liquids of any size have been allowed again for years as long as you’re only going to the domestic part of the airport, they’re separated here)

I really hope to see it. The TSA going away is my current measuring stick for whether DOGE has actually accomplished anything significantly valuable.

TSA including all of its security theatre was on life support because of insurance premiums - it allowed some creative actuarial accounting that shifted responsibilities and reduced insurance costs for airlines in post-9/11 insanity
