What if I’ve given/Found pictures that puts A person of interest/Photo evidence of a suspected shooter at the crime?

Get attorney before they get you for accessory to that crime

I would contact the FBI, long ago. The pic can be entered into evidence.

If I could help solve or prevent a crime than yes I would do so

Dont waste your time. If they were interested in the truth. they would have declassified everything long ago
