"HOCKEY - In Canada a minor league hockey coach in Hamilton has been charged with threatening to kill a teenage referee following an outburst over a two-minute penalty. Following his ejection from the game, the 34 year-old coach went onto the ice and threatened the youth official in front of his 10 and 11-year-old players and adult spectators. (March 2001)"
Wow, that hits close to home, here's another article on the topic published by the local newspaper.

Abuse of officials is a very pressing issue in this day and age. People don't realize that we give up our time to train and our time to work all of these games so their children can play in a safe environment.
But honestly, who can say that the thought of retaliation to a situation like this has never crossed ones mind?? Most of us just never act upon it.
