Using specific words and phrasing with the government to get a desirable outcome is literally what some of us have to do with the police.
True, I've never had to memorize a script to deal with the police. Don't feel necessary.
On an unrelated note, sovereign citizens are super weird.
Several years ago I used to work with a could3 of cops, and I'd always ask them: is there anything I can do during a traffic stop to get out of a ticket. They'd share laugh it off and say "no, if you deserve a ticket then you'll get one". But then once night on a business trip I was out drinking with one of the guys and asked again and he actually told me what I should do that will give a 'signal' that I'm 'one of the good ones'. I have only gotten warnings since then.
The advice was: get out your wallet, turn on the inside light, roll down your window, while holding your wallet, place both hands (crossed) at the top of your steering wheel.
I think you're right, had multiple encounter with police, don't need to memorize no scripts, and think sovcit is a bunch of insane people. So thank god for that i guess.
"I would like to talk to a lawyer before answering any questions" is my magic phrase. It is fairly easy to remember.
