Yeah, whenever I see videos where cops tell them that they are not cooperating when being silent after pleading the fifth, I get furious.

You are NOT compelled to answer any questions until a lawyer is present. Not answering questions does not and in no way constitute being uncooperative. Cooperative simply means following lawful orders, so even refusing to follow unlawful orders is not obstruction, uncooperative or whatever excuse they want to put on you.

Sadly, it’s probably better to let the manchild have his power trip and complain about it afterwards. Prevents acute lead poisoning.
