Washington, DC transit officials launched an investigation on Tuesday after learning of a video that appears to show a Metrobus driver forcibly throwing a passenger off a bus and straight to the ground. A Metro spokesman called the driver's actions "completely unacceptable" and noted that "appropriate action" would be taken against him just as soon as they figure out who the hell he is. Because they don't know.

But they do have a plan! See, once officials track down the video's uploader (again, no clue), they think they'll be able to have him or her ID the driver. So basically, they want the second person they haven't yet located to help them find the first. You know, the one who happens to be their own employee and whose face was captured on video. That guy.
