Analyzing ex-Canton officer’s testimony; will Michael Proctor be called?

A former Canton police officer called by Karen Read's defense got into a heated exchange with one of the lawyers in court as he accused her of changing her testimony since speaking to federal investigators. We ask our experts what they thought of the exchanges, if she met the definition of a hostile witness and about Read's claim she's part of a "blue wall of silence." Plus, how the jury reacted to a dog bite expert from the first trial and, after childhood friend of Michael Proctor's takes the stand, our experts weigh in on whether the defense will — or should — call the disgraced former trooper at all.     You can watch the TV version of this episode — and all the others, as well as video from court as it happens — on our YouTube page.
