Now that I think about it, WHY DO I NEED TO KNOW THE MECHANICS OF THE DATING PROCESS ANYWAY?
Because it's possible, as the group in your example did, to cast fradulent suspicion on a test procedure by tricking them into performing the test on a sample it's not meant to test.
If you send in cat piss for drug testing, and you get funny results, can you use that to overturn your marijuana conviction? Of course not. Human drug tests work on human urine. When you send them samples that they're not designed to test - like rocks with xenoliths, or with known nonradiogenic argon composition - it's no surprise you get wrong results.
But that's not the test's fault.
If I sent a rock sample to the "best" lab for dating, their results should show the date for the sample in question, or mankinds best attempt to date.
Why? Not all tests can be applied to all samples. Your guys applied the wrong test to the sample. What a surprise, since they've been doing that for years in a fraudulent effort to discredit a procedure
not used all that often anymore.
