Bank Robbery, a true tribute to Halloween

I work in the financial district. Yesterday around 1 pm there was a lot of police in front of our building, and a lot of FBI (they don't have uniforms and their cars are not marked, but somehow they are still easy to spot.) Here is a note released to tenants: "...Please be aware that our bank on the street level was robbed earlier today at around 1:00pm. The perpetrator was Caucasian, dressed in black with face paint on similar to the "Joker"..."

Let me see, if I can profile him... he watched "The Dark Night" movie... Police should now hit all Halloween parties in the city and get a list of all Caucasian men wearing "Joker" costumes. He is unlikely to invest in a different outfit considering how appropriate this one is for Halloween. What a fun assignment for an undercover officer on Halloween!
