Evidence integrity

Preserve. Do not manufacture.

Do not induce extra messages, misrepresent your identity, alter evidence, submit fabricated reports, harass or extort anyone, or opt into campaigns to manufacture claims. Recording calls can raise jurisdiction-specific legal questions. Preserve voicemail audio you already received, but seek qualified guidance before making a new call recording.
