"Sir, you are being placed under arrest. You do not have the right to resist. Please immediately turn and face the wall with your arms behind your back, or lie face down on the ground. If you do not do so, I will use physical force to ensure your compliance. I do not wish to injure you, but if you do not comply, it will be at your own risk. You are commanded to comply with my order NOW."
Not that anyone asked me. But if the police were required to give such a warning to any unarmed person who appears prepared to resist arrest, Eric Garner might be alive today.
