Daniel Penny, a 24-year-old Marine veteran, has surrendered to the New York City Police Department to face criminal charges in connection with the death of Jordan Neely, a 30-year-old former Michael Jackson impersonator who was homeless. The Manhattan District Attorney's Office has said that Penny is expected to be charged with second-degree manslaughter, and the incident has sparked outrage and calls for an investigation into the death of Neely. It has also prompted a national conversation about police brutality, the use of excessive force, and the role of bystanders in such situations.
