Here is a link to the recording of the *other* heartbreaking incident where the parents decided to hide a tape recorder in their 5 y/o son's pants. Apparently, he was crying about school on a daily basis and, thank goodness, the parents trusted their instincts and ultimately this teacher was suspended. Warning: listening to this is heart-wrenching... but it is a good reminder to trust your gut when it comes to your kid.
