Just gonna throw this out there... Let's say that a business is discovered to be a front for Mexican cartels, importing fentanyl into the country. The business is owned by an American citizen. Okay to take their **** after they have been convicted? I say yes.
If charged and convicted of criminal activity, sure.
It is not "seize first" and then "due process" (despite what trump says). That is what "civil forfieture" is.
