Peter - I have read your story. I am proud of what you did - I think I would have done the same. However, the way the crazy laws operate these days you DID take a big risk.
I have been a teacher now for over 25 years and I could have been sacked 100s of times. Why? Because I comforted children who were in distress!!
Teachers are given a thorough Criminal Record check - they are trained to work with children - they are - according to their Contracts of Employment 'in loco parentis' - yet they are mistrusted in law.
Hmmm - think I'll be a Traffic Warden instead.
