Defense expert in Potter Trial to testify about taser mistake possibility

(Minneapolis, MN) -- A defense expert in the Kim Potter trial is expected to testify this week about a theory that may explain how an officer can mistake their handgun for a taser.  

The theory is controversial and some experts say it isn't scientifically rigorous enough for a jury to hear. Dr. Laurence Miller is expected to testify in Minnesota about the "slips and capture" theory, which is meant to explain how an officer can mistake their handgun for a taser.  

Dr. Miller has been criticized previously for taking established scientific concepts in neuroscience and psychology and molding them to fit police use of force cases.
