There was the variation on the theme by K-Line, which had George Bush chasing Sadam Hussein around the car (K707-8011). It was part of the Operation Desert Storm items in the early 1990s.
Actually, that was later than the original Desert Storm cars from the 90's (or at least some of the cars. I didn't follow those close enough to know when all of them came out, maybe a few were after the Osama and Saddam chase cars). The Operation Red Dawn car, as well as a "Get Osama" car came some time after 9/11.
I seem to recall the cars were announced before Operation Red Dawn occurred that captured Saddam. They were updated graphically, I believe as the operation occurred in between the announcement and the actual production.
I thought of these cars when I saw this thread, but I think it depends on what we each consider to be the key elements of a given car to make it a Cop and Hobo variant. Personally I'd probably consider any gondola with some sort of crates in the middle that the figures revolve around in the "family". Not sure I would consider these since they were flatcars. (Obviously a very similar mechanism, and nearly identical premise, though)
