 is significantly greater than one. In practice, however, when the random match probability is low—that is, \(\Pr(\match \pmid \neg \source)\) is low—the likelihood ratio should be significantly above one because the probability that the individual who is the source would match, \(\Pr(\match \pmid \source)\), should be high so long as the test has a low false negative rate. For practical purposes, then, a low random match probability does count as strong incriminating evidence.
