NHL referees should do their jobs

Make it mandatory for officials to call the penalties within the game that occur. Players who create infractions of the rules during play should be assessed the appropriate penalties. Included are any strike of the head area or causing potential head injuries by "boarding" to be properly assessed and fines and/or suspensions handed for obvious intent to injure another player. By not assessing penalties and allowing the "let them play" mentality creates an atmosphere of anger and potential player injury.
