Which U.S. Supreme Court decision explained that teachers and school administrators only need "reasonable suspicion in order to conduct a search unlike actual law
enforcement officers?

I believe it was The U.S Supreme Court of New jersey

There are two principle kinds of voting frameworks that can prompt distinctive gathering frameworks. These are "first past the post" or "champ take all" frameworks from one perspective and relative portrayal frameworks on the other. Each of these will tend to prompt an alternate sort of gathering framework.

Hope this helps
