BS... this
supposed FBI guy couldn't make the simple private property trespassing infraction/misdemeanor arrest as you stated he did even if he wanted to. He simply doesn't have the lawful authority to do it. And a
supposed local law request doesn't change that in any way. Why are you doing this to yourself? Please quit attempting to bluff your way through this BS and let it go.
