On youtube.
Mostly just oikish behaviour, some of it taking place on the school premises & whilst in uniform - school clearly identified in captions/tags.
Head teacher has been made aware (by a senior colleague) - isn't rushing to do anything about it.
However, one clip shows students I know chanting some fairly ugly racist stuff. It's out of school so arguably absolutely nothing whatsoever to do with me - but I know these young men (& some of their parents) & am sickened.
Any suggestions?
