Although Emmet Till and Trayvon Martin were killed 57 years apart, both of the Black teenagers died for the same reasons, said Angela Onwuachi-Willig, a dean and professor at Boston University School of Law. Emmet Till was murdered by two white racists for alledgedly whistling at a white woman, in 1955. Onwuachi-Willig says George Zimmerman was portrayed as protecting a mostly white neighborhood from predation and molestation by young Blacks like Trayvon Martin, in 2012. She wrote a paper on the subject, titled “From Emmet Till to Trayvon Martin: The Persistence of White Womanhood and the Preservation of White Manhood.”
