"Well sir, i took a muggle womens self defence course, it was while i was with my muggle gran in canada, and they taught us to defend our selves. The whole point is to get out of danger in any means necesary. If you are being choked you can use the base of your palm to hit there nose and it will only break the nose at best, it is to save yourself. But they deffinitely told us that if we get them away from us not to keep hitting them or causing harm just run and yell... but to yell fire because muggles listen to that"
