How did they get caught? Someone turn them in? I don’t see how any surveillance or routine techniques would have tipped the FBI with just two men involved. They would have flown under the radar easily. Something here is amiss.
Probably how the FBI does all this sorta thing, they start supplying the perp with non functional components...
IIRC the KKK group contacted the FBI and told them about the plan. The FBI planted a couple of agents in the KKK group and they tracked the perp.
Well the article says, "High-ranking officials in the KKK informed the FBI of the super secret x-raygun which is similar to what the ghost busters used"
This story has something for everyone.
