Not that it matters anymore...
Amendment V: "No person shall...be deprived of life, liberty, or property, without due process of law..."
Probable cause IS NOT due process. Due process requires a trial and a conviction.
But who cares, what's one more gaping hole in the Bill of Rights matter... just throw another log on the fire.
Your rights don't apply if they are doing this in line with the other forfeiture laws. The case is technically against the property, which has no civil rights, and not against the person. Cases list like "People vs. 1996 Ford Bronco" or "People vs. $10,000."
