YOU HAVE THE RIGHT TO REMAIN SILENT!
If you agree to an interview with the FBI in your attorney’s and tell them you will be recording it, they will get up and leave. They will tell you that the FBI policy is to not allowed to have their interviews recorded.
If the FBI had enough evidence against you, they’d have a warrant for your arrest or a search warrant.
On two occasions, I had deputies knock on my door wanting to “talk”. Asked them if they had a warrant for my arrest. Once they told me ‘no’, I ordered them to get off my property or I would call 911 and ask for the state patrol to come and investigate a trespassing complaint. The Deputies left.
