We have a kilt-wearing British police officer in our midst (Al Sporrano), and there's another over at "Tom's Café" (Stu). They would be able to corroborate the UK position.
Just pulling from past knowledge gained from having lived in so many states, it's pretty much as Ham said. The key word involved here is "intent". Most places have laws that require some level of "intent" to expose a portion of one's body before they carry any judicial weight.
I would wager a guess that if the guy in question was actually charged then the charge will be dropped long before it gets to court. Most DA's don't like being laughed out of the courtroom.
On the other hand, you have the possible scenairo of someone exposing himself, by intent, and trying to blame it on the wind.
