The banning of Tomahawks!

Should Tomahawks be banned??
The NTHA seems to think so. But what would be the advantages and disadvantages of banning this hit in junior hockey??
Tomahawks in Darwin have recently been banned in junior hockey due to a lot of injuries that could of been prevented. Such as people being hit in the face, etc.
Though this may sound fine, there is also a major disadvantage of banning this.
One of those disadvantages is that when we go into state Tomahawks aren't band anywhere else, a conclusion that a lot of people think should happen is that the coaches should be teaching kids how to do Tomahawks saftly.
