'Black Lives Matter': a movement that defies definition

"Dark Lives Matter" has turned into a mantra for individuals challenging police viciousness against African Americans.

It's a hash tag, a prominent shirt motto and a development that is approximately sorted out – by outline.

Dark Lives Matter was established by three ladies who advanced the trademark amid challenges over the 2012 slaughtering of Trayvon Martin, an African-American high schooler who was shot by George Zimmerman, an area watch volunteer in Sanford, Florida.

It has a site (BlackLivesMatter.com) and a system of sections. In any case, the thought is greater than the association.

In spite of the fact that the walk where five Dallas cops were lethally shot Thursday was sorted out by another gathering, news reports portrayed it as a Black Lives Matters occasion.

"The advantageous account has been for individuals, for the media to say, 'Well, this was sorted out by Black Lives Matter'," said Tezlyn Figaro, a marketing specialist for Next Generation Action Network, the gathering that composed the occasion. The rally "had no association with Black Lives Matter."

The perplexity streams to a limited extent from the decentralized structure of the Black Lives Matter association and its authors' yearning that it stay open and comprehensive.

A demonstrator with Black Lives Matter holds up a sign during a protest in front of the White House in Washington, U.S., July 8, 2016.

"Not everybody who appears at a showing is an undeniable individual from BLM, (yet) they're invited and urged to take an interest," Melina Abdullah, an agent of the gathering's Los Angeles section, said in a discussion with Reuters in June.

Amid the standoff with police arbitrators Thursday, the shooter summoned the motto, saying he was "agitated about dark lives matter," as per Dallas Police Chief David Brown.

The association denied the viciousness in a post on its website page.

"This is a catastrophe - both for the individuals who have been affected by yesterday's assault and for our majority rules system," it said.

"There are some who might utilize these occasions to smother a development for change and enliven the destruction of a dynamic talk on the human privileges of Black Americans. We ought to reject every one of this. Dark activists have raised the require a conclusion to savagery, not a heightening of it."

That didn't stop a rush of online networking feedback endeavoring to attach the savagery to the development. Be that as it may, U.S. Lawyer General Loretta Lynch, talking about the showings enlivened by Black Lives and different gatherings, drew a brilliant line between the shooter's activities and "legitimate dissent and ensured discourse."

"Try not to be disheartened by the individuals who utilize your legal activities as spread for their shocking viciousness," Lynch said Friday. "We will keep on safeguarding your protected rights and to work with you in the troublesome mission of building a superior country and a brighter future."

Some said the most ideal approach to characterize the development is by keeping on pushing a positive message. After a vigil Friday in Dallas for the killed officers, Richmond Bunch played "Astounding Grace" on his violin.

"We have to outline out an approach to return to peace," said Bunch, 35, an African-American Dallas occupant and Black Lives Matter donor. "The person who submitted this demonstration, he doesn't remain for what America is."
