Craig's List Prostitution Sting

Nashville saw 18 arrested in a Craig's List prostitution sting recently. Apparently these Craig's List stings have been going on around the country. Unbelievably, I know a couple of people on the list. I almost didn't look at it thinking I wouldn't know anyone, but was then surprised. I feel badly for those I know, even though they did it to themselves. Just for fun, I looked at the "casual encounters" listings on Nashville's Craig List. I wouldn't in a million years go meet these people who I don't know like that. I guess I just don't understand why anyone would put themselves in that position.
