you can learn alot about naked shorting from the powerpoint presentation at businessjive.com (it takes about an hour to watch but it is VERY informative)
also if you go to the sec . gov website under Regulatory Actions box and click on Proposed Rules, you'll see an call for comments on "Naked" Short Selling Anti-Fraud Rule. Click on the "are available" link in that section then go to the bottom of the list and look for a submission by DeCosta. It also explains quite a bit about the technicalities involved in the naked shorting game.
It's not for you if you are into sound bites and don't have patience for complexity or complication. It is intuitive that counterfeiting shares traded on the exchanges wouldn't be easy or obvious, so the mechanism involved cannot be expected to be thus. Check out the literature. Even the sec website has alot of info on it.
p.s., naked long is kind of like folks who hold what they want to "keep" in a margin account
