Is Winfrey really an attack on junk science?

The Texas Court of Criminal Appeals doesn't reverse many cases, and it's really rare to get a reversal on legal sufficiency - which means they enter a judgment of acquittal. So its understandable why everyone is excited about the decision in Winfrey, which reversed a conviction that was based mostly on a dog scent line-up.  Some have described it as an attack on junk science. Unfortunately, I don't think it is any such thing.

Winfrey did not address the admissibility of scent line-ups. For some unknown reason the evidence was never even challenged at trial. Instead of addressing the admissibility of such evidence, the court simply held that the scent line up was not enough to support a conviction; along the way noting that at best the scent line-up shows the defendant had contact at some time with the victim's clothing. There was nothing else to establish guilt. As I noted earlier, the real physical evidence actually excluded Mr. Winfrey.

A concurring opinion did make note of the scientific criticism of scent line-ups. However, whether they should be admitted is still an open question. The Innocence Project has already addressed the problems with such evidence, which are many. This evidence still needs to be challenged, and hopefully it will not admitted. If not, we will soon see a decision on whether scent line-ups have any place in a court of law.

Moving accountability back up the line

Yesterday the Texas Court of Criminal Appeals struck at least a partial blow against junk evidence; some have said junk science, but I hate to use the term "science" for something that has absolutely nothing to do with science. The Court held that evidence of a dog scent line up was not enough to establish guilt - which to me was not that difficult a decision.

If you told someone on the street that someone could be convicted based on a "scent lineup" that was conducted using evidence that was several years old most people would think you were kidding. The process was that something from the suspect and five others were put in cans, and the dog then went and smelled each can. He alerted on one can - the soon to be defendant - and that was it. The amazing thing is there was other physical evidence - bloody fingerprints and hair. None of that matched the defendant though, so the State had to go with the dog.

My question is how you get to a conviction in a case like this. To start with, no prosecutor should ever take such a case - especially when other evidence contradicts the dog scent. We are led to believe that the when a prosecutor oversteps his authority there are some checks in place. One is the judge, who failed to see anything wrong with such evidence. The other is a the jury - people who would never believe such evidence - unless it was presented by the State. Unfortunately, that is often enough. Imagine the reaction if a defendant tried to present such evidence to show someone else committed the offense - my guess is it wouldn't even be admitted.

I'm glad Mr. Winfrey has finally won, but it should have never gotten this far. He goes home, and everyone else goes about their normal lives. That has to change. We need to move accountability back - it starts with the police who use such evidence, and goes all the way through the judge and jury. Until we figure out a way to do that, there will be more cases like this; cases where we will sit around scratching our heads wondering how someone got convicted in the first place.

Revolt at the Forensic Science Commission

The big surprise yesterday was that the forensic commission showed they finally had enough. Ever since John Bradley took control the other members have been superfluous. He has controlled the agenda, and prepared the reports. Apparently it was no different for the report on the Cameron Todd Willingham investigation. Bradley had a report ready which absolved the fire marshal of any responsibility - they were just doing the best they could do at they time. The other members finally revolted, and refused to go along - good for them.

Although I wasn't there, I heard it got fairly contentious. Bradley even told the members they were "shirking" their responsibility - seriously. In my view they finally stood up and exercised their responsibility. They have a duty to investigate - not whitewash. Mr. Bradley apparently views their responsibility as the equivalent of  his - which was to do everyone possible to either derail or minimize the impact of the Willingham case. I was convinced he was going to be successful - thank goodness it looks like that may not be the case.

We will wait to see what happens in November. But for now, the commission appears headed in the right direction.

 

Time to Abolish the Fire Marshall's Office

The State Fire Marshall system has always been a mystery to me. There is an inherent conflict in having arson determinations made by the body that regulates insurance companies; companies that have an interest in seeing fires declared as arson, so they can avoid paying claims.

There's also the problem with the competence of fire investigators in general. Over the last several years more people have recognized the role of science in arson investigations. The result has been that many of the factors relied by arson investigators are not indicators of arson, but instead, things that exist in almost all fires. The problem is at the forefront of public opinion due in large part by efforts to focus on the case of Cameron Todd Willingham - who almost everyone agrees was convicted on findings that have now been discredited. I should now say everyone but the State Fire Marshall.

The Texas Forensic Science Commission is meeting today to decide what to do about the Willingham case. Following their last meeting they solicited comments, and a number of experts provided their opinions. The main question was what the state of knowledge was back in 1992 back when the fire was originally investigated. That was around the time NFPA 921 was published - which everyone agrees was slow to be adopted by the fire investigators. As a leading expert - John DeHaan notes - there was always a conflict between the scientists and those in the field. It took awhile, but by now most agencies view NFPA 921 as the guide for fire investigations.

There was a reason why the Forensic Science Commission was focusing on what was known at the time; they were trying to give the fire marshall a pass. Even the commission chairman - John Bradley - has conceded that the investigation was flawed. There is  a reason for that - every expert who has looked at the case agrees the investigation was bad. Apparently the fire marshall - Paul Maldonado - didn't get the hint. He published a response standing by the original findings. According to Mr. Maldonado, the principals and techniques they used in the original investigation "are linked to NFPA standards subsequently put in place." In other words, he admits they should be judged by the standards that are now accepted.

It gets worse. He actually discusses the evidence, and how the original findings were consistent with NFPA 921. The argument basically tracks that used at trial, which is what has now been discredited. If Mr. Maldonado believes the original investigation and findings were conducted in accordance with current standards he should be replaced immediately. Even someone with no fire science background can see how NFPA 921 contradicts the original findings. Apparently, Mr. Madonado concedes that investigations are being conducted just as they were in 1992.

I find it difficult to believe Mr. Maldonado seriously believes what he claims. Instead, I think it is a blatant attempt to save face. If so, it shows the inherent problems with the fire marshall's office. Any "scientific" entity should be concerned with the truth and not saving face. It's time to turn arson investigations over to those who are willing to apply the science, and apply the scientific method. That's not going to happen until we change the system.
