Looks to me like any of us are fair game for the FBI under its new mission.
It may well be the FBI will take on a larger role in investigating targets chosen by the Department of Justice, and then pursued for one reason or another by civil litigation where it's iffy if laws were actually broken. The burden of proof is much lower in civil suits as compared to criminal law.
Any big cash settlements coerced from defendants by a plaintiff DOJ will be used for our protection, they'll tell us.
Update for January 19th: Looks like FBI has had a change of heart. Someone at DOJ run a focus group on the new mission statement - and realize it bombed?
