Requiring pre-registering parties is dangerous precisely because it is a control lever and a slippery slope. Students and administration will always disagree.

Requiring pre-registering parties is dangerous precisely because it is a control lever and a slippery slope. Students and administration will always disagree. Ergo, any requirement that can be abused by administration eventually will be abused. Exactly as apparently happened here. The only check is to prevent that lever from ever existing. Anarchy has many problems, but its foremost strength is standing in direct opposition to outside control. And that's an unfulfilled and critical need in our modern society, as liberties are bricked up bit by bit. (And before someone tosses it in, we can have the militia vs police end debate some other time, because "a bunch of college kids getting in trouble" is far short of anything that serious to themselves or the surrounding community)
