notguilty,
First, welcome to the AntiPolygraph.org message board. I'm sorry to learn of your polygraph experience. It is one that has been shared by many other law enforcement applicants. AntiPolygraph.org's purpose is to expose and end such abuse.
Your rights to your polygraph records will be governed by your state's public record access laws. (You'll probably find the text of the relevant law on the Web.) Not knowing which state you are in, I and others can't provide much more specific guidance than this. (If you're willing to mention what state you're in, I or others could probably help in tracking down the applicable law/s.)
Whether or not you'll need to hire a lawyer's services, it might be worthwhile to seek a consultation with a local attorney who is experienced in labor law to talk about your legal options. Martindale-Hubbell's
Lawyer Locator website is a helpful tool for finding one.
I hope you'll consider working with us toward the abolishment of the pseudoscience of polygraphy. One simple way you can help is simply by telling others about your experience and about AntiPolygraph.org. The survival of polygraphy is completely dependent on public ignorance of how the "test" really "works" (and doesn't).
Another thing you can do is to write to your federal, state, and local elected representatives about polygraphy, specifically requesting that polygraph screening of applicants and employees be abolished. (See the AntiPolygraph.org
Get Involved page regarding this.) And, of course, your participation in the public discussion and debate of polygraph issues is most welcome on this message board.
