I always thought Bell was called for targeting because he "launched". Your video shows Bell's left foot clearly is on the ground when his shoulder hits the badger in the chest. What else is Bell supposed to do?
I'm not saying Bell should have been flagged. But, I always thought he was flagged because running the way they were, he could have simply pushed the guy with his hands and he would have been out of the play. It's clear he went for the big hit even though technically he hit him with his shoulder and possibly didn't launch.
