This has piqued my interest, prisoner Medina would know if the MAGABomber was the FBI informants that got him to participate in planning a fake synagogue bombing
Where is James Medina?
Their concern includes instances where the informant, or "confidential human source" in bureau parlance, offered to assist Medina in attacking the center, and even suggested that he link the attack to the Islamic State.
Note that last bit, remember the mock ISIS flag in one of the MAGAbomber bombs?
