A homeless man was murdered on a NYC subway for doing nothing more than screaming that he's hungry. Then the Mayor calls it a "tragedy" related to "mental health issues" rather than a murder for which the murderer must be held accountable. A tragedy here is that so many Americans are so desperate that they're crying out for food in the middle of a subway; the mental health issue applies collectively to a society that can't break through this vicious cycle; and the question remains why no one in the subway car yelled out "STOP IT!!!" as they watched him die.
