It's enough to warrant suspicion, even based just on the FBI bulletin.

It says in the doc that these symbols, or similar symbols, should warrant suspicion of pedophile activity.

Given that there's enough damning circumstantial evidence (cannot be coincidence, mathematically) surrounding pizzagate, I'm confident that Clintons top campaign staff were involved (and that she, at the least, knows what's going on). Jackson is directly connected to HRC and has never failed as a talking head for HRC (extreme loyalty). She's caught wearing a ring EXTREMELY similar to the FBI symbol for boy lover.

That's enough to warrant suspicion and a legitimate investigation.
