I know all about bwi, I am one of those men you speak of. What I'm curious about is that there are busts?
Yep, due to the Craigslist thing and Baltimore backpages...it maybe the slip ups that the women or the men do...most of the drivers (cabbies, etc) know what these womb are about, and airport security sometimes gets them as well.
Sometimes it's commotion that happens in the rooms (argument or fight with the woman---whether it's over money or drugs, or services rendered) front desk may call the police--- then there is the pimps, which either beat the women or clients. Or women being held against their will. So, what happens is that local LE keeps their eyes out for potential shit that may happen
I've seen a rare one---a black latina who is a "cutter", came up here for a Comicon with a gay friend...unreal.
