Dear PoPville – What to do when a Metro Bus is flashing, “EMERGENCY: CALL POLICE”

Dear PoPville,

I saw this [“EMERGENCY: CALL POLICE”] on my way to work this morning, and all I could think was that Keanu Reeves and Sandra Bullock were on board trying to make sure a bomb wasn’t going to detonate. Any ideas? I’ve heard of other people seeing this before, so it made me wonder if bus drivers just accidentally push a button or something.

I guess it’s an example of better be safe than sorry and just call 911 and let ’em know when and where you saw it.
