When someone is out of control, throws anything hard and hurts someone or narrowly misses...it's time to call 911.
Confronting them puts our lives in danger. Letting the police do what we pay them to do is the right thing.
I know we all think "he wouldn't really hurt anyone" but I can tell you that when they are angry and out of control, people get hurt...or worse.
You did the right thing, even if you didn't mean to.
