Today, I talk with Minnesota’s lawyer-scientist, Charles Ramsay, about the law and science behind DWI testing. We discuss the importance of understanding the uncertainty of measurement in DWI testing and how it relates to both breath and blood tests.
Chuck explains that presenting test results as a certainty is misleading and that it is crucial to inform the jury about the uncertainty involved in these measurements. He even goes so far as to say that not giving the uncertainty is a Brady violation.
We also delve into the impact of interfering substances on DWI testing and the need for better science in forensic testing.
