In theory, ANYONE, could be impaled with the tip of a pole. Not every flag pole has a round end. Many flagpoles have Eagles on the top, with a pointed head. And no, if you hit someone HARD enough, you can break even a very sturdy pole, now with 2 sharp ends, and a potentially VERY deadly weapon, if the attacker can get close enough
You weren't there. This officer was being attacked, and if not for defending himself with his weapon, could have easily been seriously injured, even killed
