in the spirit of the times

The cop who's pulled you over says "Sir/Ma'am, would you open your trunk now." What do you do? Check your handy pocket reference card. (Well, it's probably a better idea to read it over beforehand. Nolo is good, too.)

Dollars to donuts the cop does not have sufficient cause for a search and is asking for your consent. Don't let him waste his time on you -- let him go catch an actual criminal.
