The problem is that the Feebs have been really good at stopping terror attacks… when they were the ones grooming the terrorist, providing materiel, recruiting other “terrorists” in the form of other undercover agents… and not much else besides investigating Catholic Churches and old ladies walking between velvet ropes waving American flags.
When I was on, the dudes from Achilles, the Marshals and the Postal Inspectors were all good people, but half of the Secret Service folks (and I worked with a LOT of them) and the FBI folks were 100% d-bags.
They're just picking on the lowest risk/easiest to track targets, looking for a pat on the back from superiors while knowing they've accomplished nothing.
I'm not even totally sure it's politically motivated, it's just that people on the right are less likely to kill your family for coming after them.
