Pro Hockey Player taken down with a single puck

Just like basketball invented in Canada created opportunity for minorities, we have hockey solving the active shooter problem. Houston we have a solution. Active shooter on campus, puck him. Yes folks next time you see an active shooter look for a hockey player, they always have a puck to throw, and if they have a stick handy, splash one active shooter. Warning if that player is  artturi-lehkonen, run, he will not be helpful in hitting a target.
