The UN's purpose is
"To maintain international peace and security, and to that end: to take effective collective measures for the prevention and removal of threats to the peace, and for the suppression of acts of aggression or other breaches of the peace, and to bring about by peaceful means, and in conformity with the principles of justice and international law, adjustment or settlement of international disputes or situations which might lead to a breach of the peace;"- United Nations Charter, Chapter I: Article 1: Section 1
the other sections reference international friendship and equal rights, but section 1 is the meat f why it exists, the UN was created after two World Wars, it's primary goal is to prevent a third and has so far been overwhelmingly successful.
The BCPD didn't throw anyone in the back of a van and kill them so that puts this as a successful interaction, and a scathing indictment.
