Dr. Jean McGuire was stabbed in Boston last month. She is a black 91-year-old "civil rights pioneer." My "radar" went off but the perp's race was withheld from the public; try searching & it will not be easy to find the info. My point (widely held here): the truth about crime is actively & forcibly kept from the public. What can be done? Once incarcerated, people like this need to be tested for low-activity alleles & those found to have those should be subject to extra confinement.
