The Black Lives Matter (BLM) movement was formed in 2013 to bring attention to the plight of black people in America and to campaign against violence and systemic racism. African-Americans are five times more likely to be killed by police than white men in the U.S. The summer of 2016 saw still more black men shot by police. Activists responded with marches and protests that have been very effective in getting public attention. But amidst these accomplishments there has also been backlash, with some suggesting BLM protest tactics may hurt more than help their cause.
