as dr. k showed what science can do in a courtroom, but in the process it showed how bad so many of the other so-called scientific tests are. dna can tell you within a percentage certainty that there is a match between the test sample and the test at a crime scene. none of these other technologies have that kind of validation studies behind it, and without those validation studies, you have an enormous possibility of misleading jurors about how good this science is because mostly it's not very good. >> dr. k, if i may call you that as well as jeff did. >> sure. >> so they thought the blood spatter could have been from a gunshot wound or from cpr. that sounds like a pretty inexact sort of thing. is it an exact science to look at blood spatter? both the former crime scene investigator, dr. k, and the m.e. director disagreed with the blood spatter finding sz yet he was in prison for 30 years. >> oddly enough blood spatter analysis is based on the laws of physics. we're looking at the size of the

because mostly it's not very good. >> i mean, dr. kf i may call you that as well as jeff did, so they thought the blood spatter could have been from a gunshot wound or from cpr. i mean, that sounds like a pretty inexact sort of thing. is it an exact science to look at blood spatter? both the former crime scene investigator, dr. k., and the m.e. director disagreed with the blood spatter findings, yet horinek was in prison for 30 years. >> oddly enough, blood spatter analysis is based on the laws of fids fidices. we're looking at the size of the droplets and the symmetry of these droplets and then trying to develop an understanding of how these droplets got on the surface to which they were observed. and so the question is not whether the evidence is lying. physical evidence doesn't lie. it's a matter of the interpretation. has the analyst interpreted properly? i think gunshot residue, for example, leaves a very fine mist, very tiny particles that don't travel very far, whereas in cpr, of course, because blood is being pushed out of a sm

there are hardly any national standards for most of the things we're discussing and, jeff, as dr. kence of the bite mark itself on someone's skin is changing. as a lawyer, what is the faith people put on bite mark analysis and evidence? >> well, it's supposed to be up to the judge. the judge is supposed to exercise a screening function and examine the science and determine whether it's worthy of being presented to the jury. a lot of judges don't do this. they pass -- let the jury decide. and there's one word that leads to a lot of injustice in these cases and that's match. you have an expert get up there and say this bite mark matches the suspect's teeth. that word match can be so misleading because we don't know how many matches there are. we don't know if bite marks are unique. we don't know what the standards are. but jurors who watch "csi" or are impressed by the credentials of an expert think match and guilty and that has led to injustice. >> sanjay, it could be used perhaps for exclusionary purposes but to include a suspect as the biter, that's dangerous. >> jeff, so there is
