What's the history around this? And don't these protections only relate to criminal proceedings?
edit: seems the parent is referring to the historical entity of the mere evidence rule which isn't the same as saying that the Framers believed a certain interpretation for the 4/5th amendments.
(4th and 5th overlap here but I generally just cite the 5th as the reason why the 4th applies is because of the 5th)
- Don't write it down.
- Delete it before you're subpoenaed.
- Mail it to your attorney.
And it is not there to protect you it is there to protect the lawyer which incidentally might protect you. It's to ensure that a vigorous defense is not compromised.
Keep your personal life to personal paper and personal devices. Don't write your life out onto something subject to discovery by someone else's legal department.
Especially if you're a C-level exec.
Policies about document and media handling are important if you're up where discovery is an active possibility. Or "have nothing to hide."
