What the heck did they suspect him of?
Maybe I didn’t read closely enough, but I don’t see any mention of what the Jackbooted Thugs were hoping to find out.
Even reading through the linked lawsuit, I can’t figure out what they wanted from him.
The only thing that makes sense to me, is that since he was already reporting to the Feds on illegal drug operations, the Feds are actively involved in or are covering up for some Cartel action along the border, and wanted to find out how much Dutton actually knew.
