What Would You Do If You Saw A Guy Watching A 9/11 Video On A Plane?

So here’s a good What Would YOUUUUUU Do? scenario for you.

Imagine this.  You’re sitting in your seat on a plane, waiting to take off.  The flight attendants are making their normal announcements about seat belts and oxygen masks.  You happen to glance over at the guy across the aisle and see that he’s watching a video on his phone.  No biggie.  But wait!  You focus in on exactly what he’s watching: a video of one of the Twin Towers burning on September 11, 2001.  What the hell?
