Agree with your post.  Schools can't win.  Everything is in hindsight.  What would have happened had the school NOT addressed the recording with the boy?  The girl's parents would have sued.  Knee-jerk reaction on behalf of the school?  Possibly.  But they couldn't have foreseen the outcome; they were just doing what they felt was correct at the moment (you know - CYA).  And given that legals love blanket edicts, are schools now supposed to call in parents before discussing EVERY infraction with a student?  What a waste of time for everyone.
