There should be bigger consequences for hits from behind in NHL.

There are always hits from behind in the NHL these days. Almost every time it happens someone gets an injury. For example, not too long ago Daymond Langkow of the Calgary Flames was given a concussion because of a hit from behind. All these players get (the ones who injure the person) are 2-game suspensions, 20-game suspensions, and 25-game suspension. There should be a bigger consequences for this. If you feel the same way I feel, sign my petition.
