Never answer police questions verbally. Ever.
Make them give their questions in writing.
Review which should (and should not) be answered with counsel (even your own).
Then answer any you want to answer very carefully.
Your answers can and will be used against you.
That is the fundamental master and servant power struggle. The master asks questions, the servant answers them.
Learn to not answer questions (see I don't answer questions on youtube) and assume the role of the master... ask your questions and they will soon find some reason to leave you be.
So true. So many people don't see what is going on or what role they are being regulated into by failure to assume the role they rightly occupy.
Of course, our schools teach people to be obedient. You will never be rewarded for questioning your teachers or demanding that they answer your questions.
Rozsencrantz and Guildenstern are dead has an amazing questions game. Get good at this and you can beat the authoritarians every time... especially once you start realizing that they have no authority until you "consent".
