Not all seizures are unreasonable. Develop Probable Cause , get it approved by management and a DA or Assistant US Attorney. Then seize. I always knew when I appropriately seized Drug Money. The next day I would get a call from an attorney, almost apologising for taking the case. His job was to appeal the matter tying up counsel to make it administratively impossible for our attorneys to do other work. Case closed.
I don't give a damn where the money came from. Civil asset forfeiture without a related criminal conviction is always nothing more than raw theft by the state. All those who take part in it are no better than any other thief.

Horse manure. You were a thief with a badge. No more, no less.
Read the effing Constitution and Bill of RIGHTS (not permissions).
No person shall be deprived of life, liberty, or property without due process of law.
That includes those YOU think guilty.
Deprivation of rights under color of law. YOU belong in jail.
