An unarmed black teenager has been shot dead by a police officer at a Wisconsin home - just days after the release of a damning report into racial prejudice by cops in Ferguson, Missouri. Tony Robinson, 19, who was suspected of a recent battery, was reportedly gunned down by officer Matt Kenny, 45, who had followed him into an apartment in Madison at 6.30pm local time Friday. A struggle had ensued in the seconds before the shooting, it is reported. The officer then performed CPR on Tony and the teen was rushed to hospital. However, he later succumbed to his injuries. The killing, which sparked a mass protest outside the home, came only two days after a Justice Department report revealed that seven racist emails had been sent by officials in Ferguson. It also came just hours before President Barack Obama will lead this weekend's 50th anniversary of 'Bloody Sunday', when police beat protesters marching from Selma, Alabama, to Montgomery.
