Re: In other news, Timmy McVeigh was not found on a single protest image
My exact thought.
a few undercover FBI operators who didn't think their right-wing incitement
As the guy responsible for the security of one of the student protests in Eastern Europe more than 20 years ago I had to deal with that first hand. 50%+ of the "violent protesters" were on the state or opposing political party payroll and were seeded in order to provoke a "proportionate" response from the state and/or ensure that we had bad PR. They "pretended to be on our side" only as much as needed to join the protest so they can do what they have been paid for.
That did not work as expected. They found it difficult to be violent protesters after our own security detail (which they were not yet aware of) counted the steps on the rear staircase with their behinds. From the third floor to the ground floor. Several times.
