The Tragic Subway Chokehold Incident and Its Aftermath.

A 30-year-old homeless man, Jordan Neely, was killed by a 24-year-old Marine veteran, Daniel J. Penny, on an F train in New York City. Neely had a history of mental illness and violence, while Penny claimed he was protecting himself and others from Neely's aggressive behavior. The incident has sparked controversy over race, homelessness, and the use of chokeholds. Neely had a troubled past, including the murder of his mother when he was a teenager, while Penny had spent most of the last several years outside New York.
