Trayvon Martin Killing Inspires 13 Tweets From Celebrities

America is in an uproar.

The lack of any official charges of murder following the shooting death of 17-year-old Florida teen Trayvon Martin has resulted in tributes, petitions, and plans for a million-man march (dubbed #millionhoodies) in New York City. Martin was on his way back from buying Skittles and iced tea from a local store on February 26 when he was shot dead by a neighborhood watchman.
