IIRC, Camille Cosby also blamed ‘Whites’ for the murder of their son, Ennis. It turned out to be a Russian, so ‘White’, but it was a crime of opportunity. Not racism.
Yes she did. He was changing a tire off the 405 freeway and a Russian thug robbed him and killed him. This old "racism" tune has about had its day. Cosby is guilty as hell and it's a travesty it took this long to convict him.
