The jury in the trial of Daniel Penny, the Marine veteran accused of killing a homeless Michael Jackson impersonator, Jordan Neely, on a New York subway last year, told the judge on Friday it was  deadlocked on the first charge, second-degree manslaughter. The judge gave them what’s called an Allen Charge, directing them to continue their deliberations. The jury then sent another note, asking for a clarification on the definition of a “reasonable person” using “physical force” in a given circumstance.
