Does not surprise me, if you choose to open carry like I do, I have my CCW/CHL so i can carry in the car without all the hassle. I have had only a few police give me issue, I would advise a tape recorder to be carried just like another magazine, it can be a great tool for a lawyer to use on your behalf. I have never be arrested for carrying openly and it is best to figure out what and how much you will speak with the police before they ever stop you. Practice saying it so you do not say something you do not intend do to the excited environment.
Understand the law and recite what you feel is necessary but do not get into a ******* match with the police you will loose that battle.
If they are going to violate your rights, make sure your recording them on tape saying what they are attempting to do and what probable cause they have to do it. That way it can be used against them in court, it will make your tape a golden egg Make sure you buy one that is PW protected, not saying they will delete the file of the incident, but "accidents"happen when you catch them crossing the line.
