Targeting quarterback with helmet

The Edmonton Calgary game Thursday was horrific. It started with Calgary spearing an Edmonton player with his helmet and was penalized early in the game. Then Calgary kept up with this strategy targeting our quarterback and put him out with a spear? No penalty? Then because they got away with it they spears our backup quarterback right in the back and put him out too? No penalty? It’s seems like Calgary had a plan to spear with there helmets and they were very successful putting several players out why are they allowed to do this?

Yes I thought I saw a few illegal hits with the Cowtown player leading with the helmet... In fact it seemed to be that was how the Canuck WB. Got hurt
