No feds aren't citizens in the US in any conventional sense. They have qualified immunity and a special kind of sovereign immunity that even state and local police do not have. They can initiate violence whereas citizens cannot. They can shoot a fleeing person as a citizen cannot. They can lie to you freely but if you lie to them (their interpretation of a lie), a felony. They generally can't be held accountable unless they are dumb enough to say the quiet parts out loud, and even then usually not.
They are also effectively impossible to sue, so you'll probably never see any justice in the courts if they act unlawfully. Even if manage to get the lawsuit going they will play fuck-fuck games with jurisdiction until you lose (as I found out when trying to sue feds for stripping me naked, cavity searching me, and executing a fraudulent warrant on a fabricated dog alert -- no one would take my case because they had lost similar cases every time).
