Protesters have gathered outside the local police headquarters in Ferguson, Missouri, once again to demand justice.<br /><br /> The demonstration was held on Thursday night in the wake of a scathing report detailing deep-rooted bias with the St Louis suburb’s mostly white police force. <br /><br /> The shooting of two police officers at another rally on Wednesday has further stoked tensions, an attack condemned by US President Barack Obama and one that has triggered a sweeping manhunt. <br /><br /> There have been several demonstrations since the killing of an unarmed black teenager by a white officer last August. <br /><br /> Ferguson is now at the centre of a national debate in the US over race and policing.
