Shelby County, TN requires some explanation here. Forever, we had two districts, Memphis City Schools, which was the much larger district, and did not spank, and Shelby County, which was the remainder of the county, and apparently did spank. Anyhow, a couple of years ago Memphis decided that it wasn't worth managing the redundant system, since we are in Shelby County too, and dissolved Memphis City Schools to create a unified Shelby County Schools. All the suburbanites got their feelings hurt by the idea of their children being in the same district (which was then predominantly composed of the old City Schools they had moved to burbs to avoid) as the ghetto kids, and all six little towns created their own municipal districts. So, whereas until about 2012, Shelby County schools was just the suburban (and a few rural) kids, it's now just the city (and a very few rural) kids. Shelby County Schools is now something very different than what it was just a few years ago.
As for this,
When I was in elementary school, my school district had corporal punishment with a wooden paddle, but parents had to sign a waiver at the beginning of the school year if they wanted their kid to be paddled for misbehavior.
clerical errors do happen. All it takes is one pissed off parent to cost a district an enormous amount of time and money in court. But then again, a lot of these Southern, rural districts aren't run with a lot of foresight, favoring tradition
uber alles.
