George Zimmerman

It's one of the most unbelievably sad stories, and at the same time infuriating. A man who served his country, and fought for his fellow citizens' freedom, killed at the hands of heartless cowards for seemingly no reason.

Celebrities and music stars were quick to take to Twitter and social media expressing their thoughts on the George Zimmerman trial. Some used words, others used art, Bruce Springsteen used his music.
