First off, let's be clear on the rules. Kingston was not a defenseless player at this moment. So forcible contact or even helmet to helmet contact isn't enough for it to be called targeting.

In this situation, the only way it gets called as targeting is if the defender launches and leads with the crown of his helmet. It's debatable in these videos whether he first hits with shoulder or with the left side of the helmet, but you can also clearly see the crown of the defender's helmet the entire time and see it not hitting Kingston. That's the 6 inch radius at the top of the helmet, and it's clear that isn't the part of the defender that hits first (or really at all).

I've been debating this one a while....but this view makes it pretty clear to me that it doesn't meet the definition of targeting, according to the rule book
