There’s no way to prove intent if you keep your mouth shut and don’t answer anything.

Yea, that’s not how it works in practice. If they catch you standing over a dead body holding the murder weapon. Then you can’t just say they can’t prove intent if you keep your mouth shut.

Yea but that's where "reasonable suspicion" comes in a court of law. If you are standing next to a dead body, with a bloody knife in your hand.

That’s good advice to not talk, but it won’t necessarily save you.
