FTFY. The fifth amendment doesn’t have any kind of “unless a judge says so” clause in it. You cannot be compelled to testify against yourself. Period, end of statement, full stop, do not pass Go or collect $200. A warrant gives them the ability to compel a search of your stuff, but it doesn’t compel you to talk.

Ask for their name and badge number. They should write it down so you can have a copy. Ask for a warrant signed by a judge. Don’t say anything. Don’t sign anything. Ask if you’re free to go. If they say you’re free to go, then fucking go. They don’t need to read your miranda rights unless you’re actually detained, but they can still use everything against you. If you’re not free to go, you’re being detained and should ask for a lawyer.

Cops will try to “interview” you in a casual setting, (where you’re technically free to go, but most people won’t think to ask), meaning they can use everything against you without reading your miranda rights. And they WILL use it against you.
