Emoji, also known as emoticons, have become so prevalent in electronic communications that their use is being cited as evidence in trials and arrests. In Pennsylvania, a man was convicted of threatening his wife via Facebook. In his defense, he cited his use of an emoticon indicating he was kidding. In Brooklyn, a teenager was arrested after police saw his threatening statement on Facebook, alongside emoticon images of guns. Police went to his home, where they found marijuana and a firearm.
