Thugs in Rochester, New York, handcuffed a nine-year-old girl, then pepper-sprayed her.

I am sure that one full-grown adult cop can restrain a nine-year-old. What did they do before pepper spray was invented?

It was incidents like this that inspired the campaign to "defund the police", which concretely means to train mental health responders and send them instead. They would have known a better way to respond to that call.
