CRI听力:Phoenix Police Officer Shot an Unarmed Black Man Dead 

Police in Phoenix of the United States have confirmed one of their officers shot and killed an unarmed black man earlier this week during a struggle.

Police say the man shot, 34-year old Rumain Brisbon, was suspected of dealing drugs outside a convenience store.

Authorities say the suspect resisted arrest when confronted by the officer, and was shot in a struggle.

Phoenix Police Sergeant Trent Crump.

"We have a duty to investigate in this particular case and he made a decision when the suspect got out of the vehicle believing that he was going to leave the area, that he was going to intervene."

The shooting in Phoenix comes at a tense time between U.S. law enforcement and the country's black community.

Two grand jury decisions not to indict officers who killed unarmed black men in Ferguson, Missouri, and in New York City have triggered racially charged protests throughout the United States.
