This would not be tampering, because you haven’t tampered with anything. The “evidence” is simply at home.

The law isn't a computer program. Intent matters.

Try proving intent when it’s a common practice. I’d even say it’s a best practice these days, especially for business.

You’re fearmongering. Find me a case of someone getting prosecuted for having a burner phone. It doesn’t exist.

If you're worried about that, you are not living in a free country anymore.
