They will scan your boarding pass, make sure the photo matches, and then escort you out. They need to check the photo before letting you out, because otherwise international transit passengers could swap boarding passes with someone else and try to escape.

There is no public airside exit that does not involve going through immigration. For domestic arriving flights, they are shunted into an arrivals corridor that allows them to either exit the terminal, or have their boarding pass scanned to enter the gate area.

That still doesn't work since zero US terminals are set up that way. You still have the issue of what to do with a plane that comes into SFO from Japan, then the plane goes from San Fran to Dulles. It simply isn't feasible for number of reasons beyond airport design though.

And an international passenger connecting to domestic clears passport control before the domestic flight and then re-enters the transit zone?

This is an issue at almost all US airports. The ideal solution would be to have terminals with departure lounges on separate floors sharing a single jetbridge. Just like non-Schengen and Schengen separation at FRA. This also solves the problem of what to do with precleared flights; the plane could arrive, dump passengers out onto the domestic floor, and then board passengers for the return flight from the international floor. The international floor would also have departure/arrival separation to ensure that arriving passengers went through security before entering the gate area.

This would be expensive though, and would make more sense for new construction than retrofits. A more practical solution would be to modify some existing international gates so that arriving passengers would be taken through corridors to the domestic departures area, and set up a few domestic gates so they could shunt people to international arrivals. This would be a good compromise between minimizing towing and minimizing construction costs.

A more practical solution for the US is to just not spend more money on exit controls. Unless surrounding the country with an actual or virtual wall and more extremely restricting/regulating people and the means of even personal/private transport, exit controls at airports are a big expense for very limited return.

Agreed. The current electronic exit control system has flaws, but they are nowhere near justifying this expense. The main issue with the current system is people who enter by air and leave by land, and that can be fixed without implementing exit controls at airports. They just need to convert the land borders to use electronic I-94's.

You can't do exit immigration at land borders without spending a huge sum of money either. There are hundreds of them, and a facility would need to be built at each one.

There were two beefy ICE officers checking everyone's ID at the exit door from the terminal to the jetbridge at DTW on June 14th, flight DL275 to NRT. I didn't stick around nor ask what/who they were specifically looking for.

Late last week, CBP had a checkpoint set up before the Canadian border on I-87 heading to Montreal. First time I've seen this. One theory is because Obama was in Montreal for an event, the other is the Canadian Grand Prix race.

If they weren't looking for a specific individual or there to put on a show of force to hassle whomever they decided to "randomly" hassle over whatever they can whip up, then it was probably just about looking for cash/near-equivalents at or above $10,000 value. Most of these interactions at DTW are money hunts.
