(Reuters) - A video posted online shows Los Angeles police scuffling with and shooting a homeless man during a confrontation, The Los Angeles Times reported on its web site. The video, posted on Facebook, shows several uniformed Los Angeles Police Department officers scuffling with a man in a downtown area where homeless people pitch tents at night known as skid row. A series of civilian deaths at the hands of police in the past year has become a touchstone for trouble race relations in the United States, most notably in Ferguson, Missouri, when an unarmed teen-ager was shot and killed by a police officer, triggering weeks of protests and some rioting. The homeless man in the video was declared dead at a hospital shortly after the shooting, the Times reported, citing police spokesman Sgt. Barry Montgomery.
