Exactly right.
No matter how "in the right" you are, police officers and all the feds are trained to try to extract incriminating statements. The questioning is called the "Reid Technique" (or Reed, s.p.?) The ONLY thing safe to say to a police officer is "I'm more than happy to talk to you as soon as my lawyer is with me". That's all you say. Period. Otherwise cooperate, let them cuff you, take you downtown, whatever. Be polite and cooperative. If they start hurting you, don't fight back, just yell as loud as you can, "you're hurting me, that hurts, you're breaking my arm ... etc.", but DO NOT FIGHT BACK. In fact, even if they are chest bumping you, don't raise your hands or push, stay relaxed with your hands at your sides, or open and above your head until they tell you otherwise. Do not allow yourself to be provoked. Most cops are fine, but there are crooked/bad ones who will try to provoke you into doing something that they can then charge you for.
And yes, I do know what I'm talking about from more than 20 years experience in the law abiding legal system.
