When it rains, it pours: St Paul crime laboratory

When it rains, it pours: St Paul crime laboratory

In an article published today by the Minnesota Public Radio, we hear an unusual story about the St. Paul crime laboratory. It’s not unusual in that there is a crime laboratory failure, unfortunately and sadly that is at least a once a week occurrence. But what makes the report unusual is that the report speaks of […]

Raymond Santana talks about the nightmare of innocence at the 2012 ACS Fall meeting (Forensic Science, Chemistry and the Law)

On August 20, 2012, the American Chemical Society at its biannual meeting held a special Presidential Seminar called “Innocence! The  Work of the Innocence Project.” It was funded by The McShane Firm, LLC and presented through the Chemistry and the Law Division and the Forensic Science, Chemistry and the Law subdivision. At the presentation, were three exonerees. […]

Readability versus trueness

Readability versus trueness

People mistake readability with trueness all the time. Imagine a full-sized live elephant gets on scale. The scale reads “113 pounds.” Not a single one of us would have any difficulty rejecting that measurement. We intuit that it is wrong. Really wrong. It’s not feasible. It’s not plausible. There is no way it could be. […]

Is forensic science truly scientific?

Is forensic science truly scientific?

There is a fundamental question before us today:  In the world of forensic science as practiced today, is it truly scientific? Or does forensic science create a veneer of science that whitewashes what in reality is science fiction? We have blogged on it before: The scientific framework of forensic science is it wrong? The sci­en­tific method […]

Yet another crime lab scandal – the real question is how many failures until they get caught and when is enough enough?

Yet another crime lab scandal – the real question is how many failures until they get caught and when is enough enough?

It seems that every week there is more news coming out of a forensic laboratory of major laboratory failures. This time it is from the state of Massachusetts where a state crime lab has been shut down and 50,000 samples from at least 34,000 different accused citizens are now all in question. Mass. Crime Lab […]

Another week another forensic laboratory scandal. It’s the Wild Wild West

Another week another forensic laboratory scandal. It’s the Wild Wild West

With no standardization of methods, a whole scale lack of basic validity, and a lack of meaningful oversight, today’s forensic laboratory system is beyond “badly fragmented.” It is utterly lawless. It is like the Wild Wild West. Like I have written before (Why Don’t we Six Sigma Forensic Science? It’s all about method validation, traceability, […]

“I don’t know” is a perfectly acceptable answer

“I don’t know” is a perfectly acceptable answer

I was reading an article. It got me to thinking about testifying expert witnesses. Basically, the premise of the article is that “I don’t know” is a perfectly acceptable answer. It is. It is a beautiful answer. It should be our default position in forensic science. We should start out with no presumptions or assumptions. […]
