You mean the way that President Obama completely “ignored” the incident of a black man shooting and killing a bunch of Dallas police officers? Because they were white? “Ignored” it by attending the memorial service in Dallas for the slain officers and in his remarks, praised the Dallas police (especially the victims) and condemned the shooter?
President Obama has always condemned senseless shootings, no matter who is committing them. He doesn’t speak out against white shooters and ignore black shooters. Trump, however, appears to be pretending that any act of violence that doesn’t fit his propaganda never happened.
