That may be starting to shift, but it is not true that American media is more sympathetic towards minorities.
"White Americans overestimate the proportion of crime committed by people of color, and associate people of color with criminality."
"Many media outlets reinforce the public’s racial misconceptions about crime by presenting African Americans and Latinos differently than whites – both quantitatively and qualitatively. Television news programs and newspapers over-represent racial minorities as crime suspects and whites as crime victims. Black and Latino suspects are also more likely than whites to be presented in a non-individualized and threatening way – unnamed and in police custody."
