Since LE and schools are both funded by tax dollars, I'm wondering if there's an element of protection in regards to liability.
The school needs, at the appropriate point, to acknowledge who screwed up, because screw up they did. MOO.
Well, lemme tell ya - I worked for a school system many long years ago - a residential facility. The head of the school only had an honorary doctorate, the head of the primary department got fired after many years because they somehow found out her credentials weren't all that. The Dean of Students ate himself into the hospital with pancreatitis while he knew there were drugs in the school, and his brother was a narc. The school psychologist committed suicide because she was having a love affair with another staff member.
Let me tell you, folks, these school people LIED, LIED, LIED. I finally had to quit and my parting words were, "...before I become as crazy as the rest of you."
Since then I've had run ins with other school systems that my own children attended. Yep, lying and covering their own behinds was still the word of the day. I had a run in with the COOK, the woman who prepared meals. I was warned she was bad tempered, but I had to call the school superintendent's office to get her to quit calling my 'phone like a maniac. Then the administrators all got together and asked if perhaps my TELEPHONE was malfunctioning. Yeah, right, malfunction with her voice on the other end and I even had a witness.
The point of this being, schools will cover themselves. They will, and they do lie, although I cannot say for a fact this one did, or will. I simply ask you to remember the Mainline Murders: Bill Bradfield, English teacher, killed Susan Reinhart, also an English teacher, and disappeared her two children - and a whole bunch of other teachers, plus a student, were somewhat involved - maybe more than somewhat. The principal of the school also ended up on death row but was released after his lawyer proved the State Police withheld and manufactured evidence.
Bottom line here, "folks", school isn't necessarily the safest place for your child to be, however, I have always found the school nurse someone you can count on.
