For the record, the quick OBL DNA match is absolutely possible.

They already had OBL's DNA sequenced (either his directly or the mitochondrial DNA he shared with siblings). This allowed them to analyze ahead of time his DNA for various unique markers that give DNA its "fingerprint". This further allowed them to develop and synthesize the tools (known as "primers) to directly look for that fingerprint in a DNA sample. Designing and making these primers is the hard part of DNA sequencing. Using them is easy and can be accomplished with use of purification kits, machinery and computational tools small enough to fit in a bathroom. Most likely a small makeshift lab had been assembled on the naval vessel the SEALS were based off of. Such an analysis should only take several hours, given they had the ability to work the conditions out ahead of time.

I have a PhD in Molecular Biology and my husband does exactly this kind of DNA sequencing for his career. We both feel the rapid DNA match is possible.

For what it's worth.
