I love in the 2nd vid how the male "officer?" comes out and (paraphrased) tells the female "officer?" to shut up and leave you alone cuz you're not doing anything wrong. As far as the 3rd vid, Did you take any action at all against the officer that pulled his firearm? If not, why not? You were on public publicly accessible land in compliance with the law yet he immediately pulled his firearm and called warning to other officers that you were armed.
In vid 4, though I disagree with the officer that you spoke with after walking behind his suv, I do like how he fairly calmly handled the situation and told you flat out "As far as I'm concerned, you're free to go."
