That is ridiculous. The idea that you can go after someone’s possessions to avoid due process is bonkers. The whole idea of civil forfeiture is archaic and should be inconceivable in a country presumably ruled by law, with its completely arbitrary character and unaccountable enforcers.
There is due process. It's just not the same standard as a criminal case. Usually it starts with the prosecutor mailing out a letter, which if you miss it means you're screwed.
