Ha!

I’m intrigued by what qualifies as “creepy video footage” …

re: the “mob” of protesters, it looked more to me like a police funeral march, presumably for a murdered Commissioner. Gordon’s clearly still in his blues when he’s talking about “knives and lint.” My guess is that the Commissioner’s murder at the hands of the Joker is one of the events that causes Bruce to rethink whether the whole “batman” thing is such a good idea.

perhaps the Joker is captured and tried for the murder, setting the stage for Harvey’s disfigurement?

Well, since the footage shown at Wizard World Chicago included a scene where Harvey is covering half of his face and someone saying that they thought he was dead, I’d say there’s an awfully good chance that he will be disfigured in this movie; leaving an excellent cliffhanger for the third film.

And I agree that it’s not protesters, but a funeral procession made up of the GCPD. The second shot of the same scene shows a casket and flowers.

I’m pretty certain it’s funeral procession of cops.

My best guess: Commissioner Loeb goes in to the cell to confront Joker one-on-one (a little reminiscent of The Mayor-and-the-Mutant-Leader scene in The DarkKnight Returns) which is where Joker’s “Why So Serious, commissioner?” scene comes in (it looks like he’s holding a black guy, doesn’t?).

He Kills him, we need a funeral…and also a new Commish.

In Begins, he went from being Detective to being Lieutenant, thus skipping Sergeant (and possibly Corporal, depending on the GCPDs rankings). I think if that doesn’t bother you, then being elevated from Lt. to Commish shouldn’t be a real show stopper.
