A "Shushing" Rule With Teeth In It

I have no idea if (or if so, how often) they actually enforce this, but in Massachusetts you can get fined fifty bucks and spend a month in jail for making noise in the library. My question is, would it be a crime against chastity, morality, decency, or good order? (Or all of the above? After all, it says "and good order," not "or.")

Sometimes I wish they had a law like this in Illinois!
