This is one of those "our money at work" stories. A 26 year-old man and a 24 year-old woman were arrested and eventually deported back to the U.K. after the man joked in a tweet about 'destroying America', a.k.a. partying it up, and 'digging up Marilyn Monroe's corpse' (joke). Even thought he pair told authorities that it was just a joke their belongings where still checked for shovels!
British tourists imprisoned and deported from US… for Twitter jokes
What I find so interesting is how DHS got the tweets so quickly. (hint-hint) People need to ponder this.
