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

What is a large sum of money?

Unless he specifies an amount I would assume anything over 10 million in cash would be large.

Heck, 10 K in cash isn't large, you can hold in your hand and that isn't very large at all.

Never Lie to a Cop, it can be considered a crime.
