That's my take. Rake or gouge makes no difference to me. Why use your hands around someone's eyes, which he clearly does by wrapping his arm around and doing what he did?From my view, it's not a gouge but regardless of what he was trying to do (no idea) it ended as a rake across the face and that's bad enough. He should get 4 - 8 weeks. It's not acceptable.
I have to ask, why? What was he trying to accomplish?
It's inherently risky, and just unnecessary.
