Guy on a Louisville stream who was released from jail, just said that as he was leaving, one of the officers told him that he should have been interviewed by the FBI, since he came from out of town. He claimed the officer said the FBI has been interviewing people that are from another state, for possible terrorism. He didn't say if he was actually interviewed.
Maybe the televisions act as listening devices, able to record in the air, and on the Tarmac.
