"Wouldn't it be the flight crew to alert the police?"
I'm not sure if the subject, Mr. Black did wrong. Who wouldn't ask Sheriff David Clarke if that was him if one saw the Milwaukee Sheriff boarding the same Northern bound jet in Cowboy clothing right after the game but apparently Clarke has his own version of what happened.
Clarke needs to watch himself. Many times, people get into trouble out of nowhere.
The other press on this is not so kind to Clarke, so I just went MSM.
