A protester speaks to the media during a peaceful protest on West Florissant Ave. in Ferguson, Missouri on August 19, 2014. Police in the US city of St. Louis shot dead another suspect on Tuesday, a short distance from a suburb that is the scene of protests over the killing of Michael Brown, an unarmed black teenager. St. Louis Police Chief Sam Dotson said in a tweet that officers had responded to a call and found an apparently agitated man, armed with a knife who yelled "kill me now" and approached the patrol.
