I disagree and here is why. Even in a perfect world with perfect integrity of the police, volunteering informtion when you are the subject of an investigation is generally a bad idea. The problem is this: "investigation" in any discipline means "finding a story that matches what I can show." This means whatever you say that matches the story will be held on to and whatever you say that doesn't match it will be easily forgotten. This is the root of confirmation bias. It's a very dangerous thing in this context. Yes there are times to talk to the police. Give an alibi along with sources who can confirm it if that is relevant. But say as little as possible. Stick to the minimal details. The less you say, the less they are likely to grab a hold of something you said and hang you with it. But remember: The job of the police is to arrest someone and tell a good plausible story as to why they are guilty. They are there to gather evidence. The DA is there to convince a jury. Nobody can know what really happened who wasn't there. So don't give them ideas.
