Hundreds of anti-racists rallied and marched in central London last Saturday in protest against racism and injustice.
Black Activists Rising Against the Cuts (Barac) called the protest.
It was in solidarity with the families of Trayvon Martin, Stephen Lawrence, Azelle Rodney, Jimmy Mubenga and other victims of racism and violence.
George Zimmerman was acquitted of the murder of black teenager Trayvon Martin in the US last month even though he admitted shooting him.
The rally began outside the US embassy in Grosvenor Square. Protesters chanted, “No justice, no peace!” in protest at Zimmerman’s acquittal.
Lee Jasper, co-founder of Barac, told the crowd, “America is infested with institutionalised racism.
“George Zimmerman has signed a book deal worth $750,000, which is proof that in America crime does pay.”
Demonstrators chanted, “Zimmerman do your time, being black is not a crime,” as they marched to Downing Street.
George Galloway MP and Brian Richardson, assistant secretary of Unite Against Fascism, and others addressed a rally at Downing Street.
More than 700 protesters gathered at Atlanta’s state capitol on Sunday to demand the department of justice file charges against Zimmerman.
