Let's just for a minute imagine that your teenage daughter and her friend went to the well populated park at 4pm one afternoon in full daylight.
Imagine how your daughter might feel if her friend was then attacked by a girl called, oh I dunno - lets say 'Jax', and lets imagine that 'Jax' thumped your daughter's friend to the ground but the friend, who was fighting for her life, managed to hold her own against 'Jax'. And lets imagine that at that point anther girl, lets say her name was 'Desiree', then leapt in and dragged your daughter's friend a metre along the ground by her hair and then started kicking and punching the friend as well.
And imagine if dozens of other kids were standing around watching. Stay with me: try and imagine it: 2 girls beating 1 girl surrounded by abut 50 kids, all just watching. Oh and recording it on their cellphones too, and then imagine that one of those girls, lets say her name was 'Eden', posted that video clip up to YouTube. Imagine then that dozens of kids in the town are emailed the video and then it is bluetoothed around school classrooms.
You can't really imagine that bit though really. No one would be so stupid as to use their personal Youtube account to upload a video which showed their friends beating up another girl, a girl whom the video shows did nothing to provoke or encourage the attack.
You would probably have no trouble imagining that the Police would take action against 'Jax' and 'Desiree' and 'Eden' so that these 'young ladies' learned that it was not okay to beat the crap out of another child. Maybe charges of 'grievous bodily harm' or 'common asault' or something like that would be laid. Maybe the school would even do something that would give the message:"This is not ok".
You would never in a million years imagine that 'Jax', 'Eden' and 'Desiree' would get away scot free because they are protected from prosecution by NZs youth laws.
