The acquittal of Marine Daniel Penny by a jury is a verdict for common sense. It is good to see New Yorkers deliver a unanimous “not guilty” decision in respect of the fatal encounter between Mr. Penny and Jordan Neely on an uptown F train at lower Manhattan. The presiding judge, Maxwell Wiley, had earlier dismissed the prosecution’s most serious charge, for manslaughter. Mr. Penny had moved for a mistrial. Now, he has an acquittal.
