VCDL http://www.vcdl.org has a link on their site to .pdf files of various laws & Attorney General Opinions, if you are interested in a convenient source. VCDL usually has at their gun show table a small pocket-sized card with basic info. I always was told that was education for the handgun owners, not something to shove under the nose of the cop and tell him to read it.
My take is that you are never going to win a case on the street, and the more papers you pull out of your pockets to "prove" the cop is wrong the more the cop will dig in his heels. If there was a chance you would not get a free ride in the back seat, pulling out and shuffling papers is perhaps the best way to kill that chance.
I know that lawyering up and settling it in court costs $$$. But for most circumstances you get to go home and wait there for your trial date(s), and can go home each day after your case in adjourned until the day the judge/jury tells you if your defense lawyer was any good.
I wholeheartedly support folks knowing what the laws/regulations are, and of course following them to the letter. But I do not see any advantage to carrying around a set of papers to wave at a cop. (Ask the Manassas 7 if it worked for them. Ask Danbus how many different laws/regulations he would need to carry, and if having them would shorten the time he is rousted about.)
* edited to add - several folks on OCDO have copied Ed's wonderful info business cards (contact him via PM for details). Those cards are a great education tool to give to the general public about OC-ing. I find myself giving out a card or 2 a few times a week.
