During a protest against the raise of tuition fees of colleges last November up to 60 students who had the intention of joining the protest were contained by the Metropolitan police. Three of those students are now challenging the Met decision to ‘kettle’ the pupils, stating that they “were locked up with no food and very little water for more seven hours straight”. They claim that the police has broke the laws of the European Convention of Human Rights, since they felt they had the right to join the protest.
Opinion
Assuming this story is indeed true, the fact that the police locked away a lot of students while they didn’t do anything to break the law is very offending to me. To protest is a fundamental right for everyone, and this is especially important to under-aged kids, since they don’t have the right to vote yet, making protesting a very useful tool to voice their opinion. I am most certainly rooting for the kids in this case, so events like these can be prevented in the future.
