President Barack Obama has said that "Trayvon Martin could have been me, 35 years ago", in his first comments on the case since last week's verdict.
The unarmed black 17-year-old was shot and killed in Florida in February 2012.
George Zimmerman, 29, said he opened fire on the teenager in self-defence and was acquitted of murder by a Florida court last week.
In an unexpected press call, Mr Obama said very few black men in the US had not experienced racial profiling.
