What the heck does that third prong on a Western Hemisphere power plug do (the “ground”) if it isn’t necessary for all electronics?

Hell, I’ve even seen people rip them off to fit 3 prong plugs into 2 prong extension cords. I’m sure it’s not safe, but I dont know why and why they would be necessary sometimes and sometimes not.

The ground allows metal cases to discharge power if a short causes the case to become live. This will prevent your body from becoming the ground if you touch the metal case.
