to have "told" the school

[ditheringnow]

Name changed as really must be secret squirrel here.
DS is sixth form at a school with a boarding component. He came home last night and told me about this

Had never heard of it but seems to be some stupidly dangerous facebook game bit like a chain letter but if tagged you have to film yourself binge drinking!
DS told me in a "how stupid is this" kind of a way (thankfully and a little suprisingly !) but he also was talking about it because two school pupils had posted facebook videos of themselves doing this, on school premises. One in a day house and one in a boarding house. This seems to be common knowledge among his year group butobv not among the staff. He showed me one video.
I have just emailed his tutor to tell him what is going on, not naming the culprits. Firstly (and mainly) because I am concerned that someones child might end up getting hurt and secondly because it could really damage the school if it came out and they had not known or done anythng about it.
I have reiterated that DS is not involved and that it must be confidential but now I am worried I should have just ignored it, I dont want to get him or anyone else in trouble but would feel terrible if something bad happened and I had kept quiet.
Cant discuss with DH as he is too honest and should the need to deny to DS and involvemnt on my part arise, he would be hopeless and confess!

You can't always stop teens drinking recklessly.

But you can educate them about it, and to a certain extent make it harder for them to do so. The school has a community of teens to look after, and their families expect this to be done properly. That includes having rules about alcohol and enforcing them.

Tipping off the school about a current issue relating to teen bravado and dangerous drinking will let boarding staff, in loco parentis, decide what they might need to do.

The school is in loco parentis regarding the boarders & has a responsibility to keep them safe. I'd've done what you did. My main concern is that they'll be sneakier in future regarding the drinking & do it away from school premises where they might be at greater risk.

Yanbu I would have done the same.

I have dealt with 'parental tip offs' at school and rest assured I ( and every senior teacher I've ever worked with) would make sure your DS is not outed as the grass.

I won't pretend we can /or would want to eradicate teenage drinking but this sounds more than this. Particularly the drinking in a day house- I would assume it therefore took place during the 'normal' school day? Before 7ish?
