I think it was unnecessary for him to reference Nazi Germany in the video. The cops messing with you aren't going to care. They're not going to consider, "Hey, he's right. I am acting contrary to the principles of liberty. My treatment of this citizen is unjust and immoral." Anyone wanting to OC needs to remember that. Most cops aren't likely to care. They've got a job to do - a paycheck to collect. Be cordial and straightforward, and hope they act cordially and professionally. Save the analogies and philosophical grandstanding for later when you can be a little more articulate.
Now then, I'm thinking of OC'ing in this same area very soon, as it is very near me. The police need to get used to it. I've got video cameras and voice recorders. I would preferably like to enlist someone else to handle the videotaping. Awfully silly that such a thing would be necessary, but in Cleveland Hts, a confrontation with the police is pretty much a given. There are a lot of them, and they seem to have pretty fast response times, and people around here just aren't used to the idea of honest citizens being armed. Recording while OC'ing in this area may be necessary at first.
