WASHINGTON: "Black Lives Matter" has become a mantra for people protesting police violence against African Americans.
It's a hash tag, a popular t-shirt slogan and a movement that is loosely organised – by design.
Black Lives Matter was founded by three women who popularised the slogan during protests over the 2012 killing of Trayvon Martin, an African-American teen who was shot by George Zimmerman, a neighbourhood watch volunteer in Sanford, Florida.
