"Mephisto (Penguin Twentieth Century Classics)" (Klaus Mann)
Disturbing
A man in Sweden didn't like the way his son-in-law was acting, so he sent a note to the FBI accusing the guy of being an Al Qaeda operative just before he took a trip to the USA. When he landed, the DHS held him in a cell for 11 hours, then deported him
[From FBI will have anyone you call a terrorist detained - Boing Boing]
Even more disturbing because for a brief second, I considered using this tactic on a particular resident of my condo building. I won't ramble on with a litany of complaints against the asshole, suffice to say, I wouldn't be too unhappy if the FBI deported him back to pre-revolutionary Massachusetts, or somewhere else where I'd never have to listen to his madness and misguided bile spew forth again.
