Then they charge you for obstruction (or whatever it's called in oklahoma, in french it's called "entrave à un agent de la paix")

It is obstruction of justice and it's very unpleasant.

If they're so inclined they can take your things by force and you will have no reasonable means of recourse.

Isn't the question, "obstructing what?"

And the answer, of course, is "Justice."

It's like being charged solely with resisting arrest.

Or destruction of government property when you bleed on them during a beating? Ferguson:

That seems questionable, how can they charge you with obstruction when you can just not answer any questions you're not legally obligated to answer.

I tried to write the long answer and it turned out as a wall of text composed of parenthetical caveats. Then I tried to right the short answer and it turned out as a medium length yet confusing answer.

The truth of the matter is that people are barely evolved ape/chimps and do pretty much whatever suites them as long as they don't get their ass kicked for it.

Thanks! I'm saving this comment for its general applicability to, unfortunately, anything.

Yes, that would be the fourth amendment.
