What rights do we have against 'civil-forfeiture' when pulled over by the police?

This is disturbing, but not surprising. Things are only going to get worse before they get better again too. Crappy part is, being 23 years old now, I'm going to be the generation that has to deal with it years to come.. I'm leaving for Canada, good beer and at least I would feel like I can stand up for the good of the people, not the jerks up stairs.
