Doubtful that you will do any of that; if you recorded an interaction it would be as stupid as the one you posted previously.
It will also serve as documented evidence of who said/did what, and it can be used in court of law against opposing party. Additionally (and this is what these bureaucrats are most concerned about) , once you publish record of your interaction it damages their image. Since they are not me, an average Joe, they are extremely concerned about their image. And are sensitive to any damage or blow received in public opinion. Their weapons are their huge resources, guns, bullying tactics, crudeness, brutality and etc. Our weapon is Public Relation actions, our speech and the recorded evidence which we are willing to publish for the whole world to see.
People in general have this false idea, that someone who wears a badge (authority figure) is their father and mother in one, a figure you can trust, have faith in, and infallible as God. Nothing is farther from the truth. And these people are NOT your parents/father/mother. Reality is that a lot of scumbags and street criminals with bad education and character apply for jobs as cops/border agents, and just as hoodlum on the street breaks the laws and covers for another hoodlum from the same block (or a criminal from the same gang), these LEOs do break the laws, do commit crimes, do lie and cover for each other when violation of the citizen's rights come to a light. When incidents happen (and they do, as evidenced by the video on my signature line), recorded video and audio are the only means of defending your rights in court of law. Without it they will lie through their teeth and accuse you of whatever they want, and bear false testimony in support of each other. So, recorded testimony is a must. Generally, anything that drives criminals with badges nuts is a prudent thing to do (to measure your words when interacting with them, to record all conversations, to post videos on your Youtube channels/blogs and hire the lawyers to sue crap out of these criminals when they violate your rights and etc.).
