Across the country, protesters rage at the acquittal of George Zimmerman.
Thousands of protesters gathered in cities across the United States to decry George Zimmerman's acquittal. Zimmerman shot unarmed teenager Trayvon Martin. The ruling was issued Saturday evening.
U.S. President Barack Obama called for calm on Sunday. "We should ask ourselves, as individuals and as a society, how we can prevent future tragedies like this," the President said in a statement.
Here's a glimpse at what some of the protests looked like:
