So the story itself is bogus, but if you've ever been questioned by the police, FBI or a Presidential Security team, (I have) you'd quickly realize that they have more info on file about you than you'd ever imagine. I've never been charged or convicted of a serious crime, yet my name popped up several times because I knew people who had.
Growing up, we had 4 FBI Field Agents living in our neighborhood. Four that didn't hide it from their neighbors (this was back in the day of the Hoover mandated wingtips and buzzcuts). I'm not paranoid, but I'm not naive either.
