In communities big and small, people wore hooded sweatshirts -- hoodies -- and carried Skittles and iced tea -- just as Martin had done on the night of his death -- as they called for Zimmerman's arrest, legislative changes and an end to racial profiling.
They included throngs of people who marched on streets in front of the Georgia State Capitol in Atlanta, decrying a "stand your ground" law in that state -- as in Florida -- that allows people to use force in self-defense.
More than 2,100 miles away in San Francisco, others held up signs reading, "We demand justice."
Similar scenes played out in Iowa City, Iowa; Houston; Detroit; Philadelphia; and places in between.
The Rev. Al Sharpton, presented Sanford's city commission with a petition he claimed had been signed by 2 million people who urged that the shooter be detained.
In Washington, D.C., a march to the Justice Department ended with the delivery of printout of an online petition with over half a million signatures demanding action.
A new poll shows that 67 percent of white Americans and 86 percent of nonwhites believe Martin’s shooter, 28-year-old George Zimmerman, should be arrested.
