daggo, you obviously skipped over the first part of this rule:
"although such violent or unnecessary use of the helmet and facemask is impermissible against any opponent" and chose to focus on the defenseless part. If you have a link to more current rules, please post them, and while you're at it, reference even in the most general terms where in your rules leading with your helmet while tackling is allowed.
