It's been a daily thing now to read reports of violent attacks, very often by a total stranger or strangers, in NYC subway now.
A guy slashes a straphanger's face, unprovoked.
A pair of teenagers hurtle Asian slurs and beats up a man, unprovoked.
A group of young men approaches a woman sitting on a bench and strangle her, unprovoked.
A woman splashes acid on another woman's face, unprovoked.
Some talked about mental health issues but some of these are clearly not. Just sheer violence. Why?
