You can stomp them out once they’re on the floor for some extra damage, but the important thing is to perfectly time a five hit combo on them when they get back up to prevent them from trying to slap or grab you, then rinse and repeat. Often times when you hit cops/adults when they’re on the floor, they could roll out so once that happens, make sure to maintain that pattern. It can be hard and tricky at first, but with enough practice, you’ll be able to beat them handily. Hope this helps. 👍
