EDIT 2:

II realize a lot of this might mostly apply to the US, so take it with a grain of salt:

"What!? Bullies get away with it because they aren't challenged! None of us are allowed our Rights because the police graciously let us have them, they are ours. They are guaranteed by the Constitution of our country and must be vigorously defended.

With that said, of course be respectful (the video might even mention this? I don't know, it's been a while since I watched it), but please, be firm and don't let anyone trample over your rights just because it feels easier in the moment."

EDIT: Also, respectfully, if you only watch body cam footage you might only see what they want you to see. There are many, many cases of police turning off their body cameras or raising the hoods of their cruisers (blocking the dash cam) with varying excuses...
