This is not it. Children have no reasonable expectation of privacy in a public school except in the bathroom. The teachers, as public employee's in a public institution, have no reasonable expectation of privacy, except in the lounge and restrooms as well.

Nope! I'm one of those types who interpret the constitution quite literally, as written. Seems to me that having your fact constantly on camera and having your every action constantly scrutinized is a violation of the constitution. Sorry you disagree.
