Regardless of the state of society, when a police officer arrives on the scene, you MUST defer to them. The reason? If they feel threatened, they might shoot you.
Listen to any instructions you’re given and follow them without hesitation. There will be time to explain once the officer feels safe.
Keep your hands in view. Don’t reach into pockets, even for identification, until asked. You may be asked to turn away from the officer.
Tell the officer about any concealed weapons you are carrying. For visible or carried weapons, the officer will instruct you how to deal with these.
