That was the first part of my answer.
This is the second part of my answer. When we receive a complaint, it is rigorously analyzed by our legal advisors. The job of these people is to determine whether a specific offence has been committed, whether there are enough facts to warrant the belief that an offence has been committed, and that there is sufficient evidence to convince a court beyond any reasonable doubt that an offence has been committed. The public interest is another element which is taken into account. This is not an easy process. Controlling incidents which happen when tensions and emotions run high is not easy.
