The Troubling Legacy of Jordan Neely's Subway Attacks.

Jordan Neely, the man who died in a chokehold on a New York City subway, had a history of violent attacks on subway riders. Neely had been arrested dozens of times, including most recently for vicious assaults on subway riders. He had a history of mental illness and drug addiction and had a difficult upbringing. Marine veteran Daniel Penny allegedly put him in a fatal chokehold after Neely reportedly threatened passengers. Penny hasn't been criminally charged, and the Manhattan DA's Office is investigating Neely's death, which has sparked public outrage and widespread protests across the city.
