Several people I know have gotten arrested on BS charges (related to being journalists/grad students and investigating the slave-labor-of-subcontinentals thing).
There's some other reasons too - as much as I'm sure I could avoid any public displays giving myself away, I'm not a fan of the idea of going to a country where the fact that I'm gay is enough to get me arrested. I've turned down work in Dubai for this reason in the past (twice) and would do it again.
