May not relate to law but it falls under exercising justice.
I was in school (higher student) when a younger student had their phone pointed at me and the flash went off. I suspected he took a photo of me as one of his friends sent me a random photo and called to me - they were playing about. I called to him, asking if he took a photo. He told me no, to which I demanded he show me his camera album to prove such. He then said it was instead a call (the LED flash was then caused by the notification), and picked up his bag to leave (the period had not ended). I stood in his way as his friend intervened telling me to leave him alone. I told him since it was a call he could prove it by showing me his call log. He refused and tried to leave - I read this as he felt he was caught out and tried to escape. I held my hand in his way and repeated my demand, but he continued to try to escape. I then held onto the strap of his bag and repeated my demand that he show me his call log. His friend continued to intervene and the student still did not show me his call log, I read this as his friend was backing the student as he tried to escape me. It came to the a teacher of high status appearing and I immediately let go. End of scenario.
My statement and his was taken. Upon entering the head of year's office she explained the boy was an 'exemplary student' who is usually quiet and never misbehaves. The student in fact did not take any photo and did receive a call. In total I am given a maximum 3-day exclusion and repeatedly told I was angry throughout the ordeal and acted unfairly - the teacher cited the boy being shaken after the event. I was told I was attacking him by holding him by the bag strap, and that I did not restrain him as the definition of restraint is holding an aggressor away.
I asked if if the boy was not shaken afterward and rather responded with aggression would the punishment be any different, as she repeatedly mentioned I caused his distress. I believe how he feels after the event does not affect my actions and should not affect my subsequent punishment.
Repeatedly I claimed I was not angry yet this was refuted with conviction by the teacher. I am now on an exclusion for this event. I believe holding someone by their bagstrap is not assault and that I am being punished in this manner because of the student's distress, younger age and the fact there was no photo taken.
Is it fair for me to reason I did not act out of line by holding him back and demanding he prove he did not take a photo of me? Is it excessive use of force?
