Was Bin Laden in fact a freedom fighter?
Again, do you not see the incredibly obvious hole in your logic? These designations are almost always a matter of PERCEPTION. The Russians considered the Mujaheddin terrorists, we didn't. Then we changed our mind and considered them terrorists later. The US considered the Viet Cong terrorists, while the population often considered them freedom fighters. Similarly, the Vietnamese considered our bombing campaigns acts of terror. As far as I can tell your definition of terrorist is 'whoever the US says is a terrorist', which obviously won't fly.
As K1052 has said your policy position opens US officials of all types open to assassination. If that's something you're okay with then just say it. If not, then you should reconsider your position.
