(CNN)The Centers for Disease Control and Prevention is now recommending that all Americans wear homemade face coverings in public to help stem the spread of coronavirus. But Trevor Logan, an economics professor at Ohio State University, will not be following this guidance. "We have a lot of examples of the presumed criminality of black men in general," Logan, who is black, told CNN. "And then we have the advice to go out in public in something that ... can certainly be read as being criminal or nefarious, particularly when applied to black men."
