I heard a report on the radio just yesterday that was alarming.
.
An older man on public transportation, a train or a bus, was sitting there minding his own business when a group of children nearby started smoking marijuana. He asked them to please stop. That's when trouble broke out. The boys in the group struck at him, punching his upper body and head, and kicking his legs. This was on security video for reference. When he tried to defend himself, a girl hit him over the head with a skateboard. He fell unconscious with a head injury and had to be taken to the ER.

This was just one incident but who knows -- once it's in the news people get the idea it's okay, somehow.
