“… Randall Vogt is offering the untested theory, called post traumatic slave syndrome, in his defense of Isaac Cortez Bynum, who is charged with murder by abuse in the June 30 death of his son, Ryshawn Lamar Bynum. Vogt says he will argue ? ‘in a general way’ ? that masters beat slaves, so Bynum was justified in beating his son.

“The slave theory is the work of Joy DeGruy-Leary, an assistant professor in the Portland State University Graduate School of Social Work. It is not listed by psychiatrists or the courts as an accepted disorder, and some experts said they had never heard of it.

“DeGruy-Leary testified this month in Washington County Circuit Court that African Americans today are affected by past centuries of U.S. slavery because the original slaves were never treated for the trauma of losing their homes; seeing relatives whipped, raped and killed; and being subjugated by whites. …”
