In your April 7 article "When the test fails," and in the headline, you allege that the drug test has failed, and that the reliability of the testimony of a known drug user and several "witnesses" (who were friends of the deceased) who had four days to get their stories straight, is more reliable than a carefully supervised laboratory- controlled test that was taken immediately the next morning. Do you really believe what you wrote? It absolutely defies common sense! I suggest that the testimony doesn't call the test results into doubt but, rather, that the test results call the testimony into doubt. Centerville [end]
