According to the Seattle Times, a Washington State trooper, Sergeant Kyle Smith, noticed a man was pulled over along the side of a busy highway. Sergeant Smith approached the car only to find that the the male drive had eight phones all logged into Pokemon Go on his passenger seat. Eight. That's eight times he clicked on the warning when the game starts to tells you to be safe and eight times (at least) he's had to click on "I'm a passenger'.
Since he wasn't actually seen driving while playing he wasn't issued a ticket but come on, we all know he was driving around trying to catch Pikachu in his latest hat.
