No such thing in my opinion. Right, depends on whether it happened to you or someone else. Yea, I've had things thrown at me by a coach, been grabbed while leaving the court by a coach, etc. If you didn't file charges then you are part of the problem.
Gutless administrators is the problem.
Ones who hire coaches prone to such actions. No, officials who don't deal with these actions harshly are the problem. Get the message out that this won't be tolerated and it will stop. I worked a youth football game on a military base this past season. I requested that an escort be available to see us to our cars after the game.
