As tourists looked on, the protesters chanted: “What do we want?” “Justice!” “When do we want it?” “Now!”
The demonstration was one of many in major U.S. cities Sunday after George Zimmerman was acquitted Saturday night of murdering Trayvon Martin in Florida.
After a protest Saturday night in Oakland turned violent, Sunday's protests were peaceful.
Lines of police occasionally attempted to redirect the New York march as it moved through Manhattan, with cabs and trucks sometimes honking in support.
"We are all Trayvon Martin!" a speaker with a megaphone told the demonstrators in Times Square, with the rally broadcast on a live feed over the Web. "Justice for Trayvon Martin!"
Beneath the glitzy lights of the square, protesters gathered and spoke with an Occupy-Wall-Street-style "human mic," with protestors repeating a speaker's words in unison for others to hear.
Then the chanters shouted, "Sit down, shut it down!" and sat down in Times Square.
Here are a few photos tweeted from the march and the scene:

Cry to "sit down" sweeps crowd. Protest becomes a sit-in, of sorts. Cab driver stuck in the middle! pic.twitter.com/ARPKeFd3xr— Ravi Somaiya (@ravisomaiya) July 15, 2013
