The Arlington, Texas police and fire departments teamed up to help grant the wish of a seven-year-old boy with leukemia.

He told a charity that he wanted to be Batman for a day, so on Saturday, he got a Batman costume and teamed up with an officer dressed as a grown-up Batman. Then the rest of the department helped stage a bank robbery by the Joker, and a city hall bombing by the Riddler, and the kid helped 'foil' both.
