Quick answer
Preserve lawful evidence promptly; recordings can be overwritten quickly.
Do now
Identify camera locations, owners, dates, and time ranges. Keep original dashcam files and public post URLs. Ask a lawyer about preservation requests and obtaining records lawfully. Keep your own posts and messages intact.
Watch for
Do not trespass, impersonate someone, or delete material to hide it from a case. Privacy settings do not guarantee a post will remain unavailable in litigation.
