Zdeno's cheap shot on Pacioretty

This hit on Max Pacioretty happened on March the 9th, and left him motionless on the ice and he had to be taken off the ice on a stretcher. The league's ruling on the hit was nothing, Chara got away with a potential career ending hit. The hit didn't need to happen Chara didn't have to level him into the metal stantions that hold up the glass. In the result of the hit Pacioretty suffered a severe concussion and a broken 4th vertebra in his neck. The thing that gets me is that Chara didn't get a fine or suspension, but a day later Pavel Kubina got fined 60,000 dollars and got a 2 game suspension for elbowing someone lightly in the head. Okay, well maybe not lightly but Bolland got up and kept playing unlike Pacioretty. This was a headshot on Bolland like Chara's hit was on Pacioretty. Kubina got 2 games and a fine for knocking someone in the head with an elbow and Bolland kept playing, but Chara got nothing for a deadly hit that left Paches motionless on the ice. The league's got to do something how can they not fine Chara and a day later they fine Kubina? There should be a rule for headshots, if someone gets a 5 minute major and a game misconduct there should be a automatic fine and an amount of games the player is suspended for. For all headshots no matter if it is a harmless play like the NHL ruled on this play, there should be a fine and suspension no matter what. Head injuries can kill your career, look at Marc Savard he has had 2 concussions within 1-2 years and they just reported he is having memory issues... This doesn't seem to be a big problem going foreward, it is an enormous one.
