FBI insiders said it is unlikely leaders of the radical groups that clashed in demonstrations turned deadly in Charlottesville, VA will face prosecution.

FBI said they have already identified several federal informants who participated in the mob-like riots over the weekend in Virginia. The FBI is also now working those sources to piece together the events from Charlottesville, sources said.  

But FBI agents have deemed the newly-minted investigation dicey, having to navigate separate agreements with embedded intelligence assets while trying to pinpoint responsibility for the violence.
