A man is detained by law enforcement while protesting the
shooting death of Alton Sterling outside the headquarters of the
police department in Baton Rouge, Louisiana, U.S. July 9, 2016.
Alton Sterling, a 37-year-black man and father of five, was held
down by two white police officers and shot at close range by one
of the officers. The shooting, captured on cell phone videos,
aggravated the unrest that has coursed through the United States
for two years over the use of excessive force by police, especially
against black men.
