A 10-year-old in Brooklyn appears to be well on his way to becoming Batman. The New York Post reports that two armed men, pretending to be FedEx deliverymen, invaded the boy's home last night, ordering two teens to remain in the living room. Then one of the men made the mistake of attempting to reach into an upstairs room, gun in hand ... spurring the 10-year-old boy to slam the door on him, causing him to drop the gun, which the boy grabbed. He fired one shot and one of the would-be robbers fired back, but both men ultimately fled. No one in the home was injured.
