How long does it take to "fingerprint" someone's DNA?

For everybody playing Armchair Conspiracy Theorist (Is there any other kind? I'm not sure.): Molecular biology Ph.D. student, and science blogger, Christie Wilcox confirms that it is, indeed, possible to run a meaningful DNA test in a few hours, or even a few minutes. Depending on the type of test you use, and what that test is looking at. In fact, you'd only need about 5 hours to run three separate DNA tests. So while there seems to be some confusion over where the bin Laden family DNA is coming from, there shouldn't be any confusion over whether a DNA test was possible.
