The same thing that is stopping them from suicide bombing the super crowded security checkpoint line before ID checks.

Nothing really.

Or going into the baggage claim area with a bag containing an explosive device, then acting like they grabbed the wrong bag and putting it back on the carousel, and then leaving.

As an aside, this is something I've only seen in the US. At least in my country the domestic baggage claim area is not accessible unless from an arriving aircraft.

I'm guessing that has more to do with theft though than security.

Do people collect their bags from the baggage claim area and then immediately reboard an aircraft to exit the terminal?

How do the arrivals exist the terminal

Are you not allowed to have a friend who is picking you up assist with baggage claim?

		often baggage pickup is on the terminal side of the ‘one way exit’.

No, that's because in the US they're handling the international flights separately. It's also the reason why even when you have a layover, you need to clear customs.

Domestic flights in the US are like busses/trains elsewhere. Most people fly without a checked bag

That sounds like bullshit to me.

		I don't know if we are the level of "most people" but I'd say we are defintely at a "signficant percentage of ppl". Due to cost of checked luggage the popularity of one bag carry on flying has exploded.

We need to put a checkpoint before the checkpoint so that never happens!

		In Uganda they make you get out of your car and go through a metal detector before getting to the pre-security security screening at the actual airport... 3-4 layers...
