Dr Brian Williams is an African American trauma surgeon who works in Dallas, Texas. When Dr Williams turned up for work on July 7th, there was huge racial tension in the air. The country was still coming to terms with the latest fatal police shootings of black men in Louisiana and Minnesota. Several 'Black Lives Matter' protests were taking place that day, including one in downtown Dallas. As the peaceful protest drew to an end, a lone sniper opened fire on the police, eventually killing five officers. Seven more officers and two civilians were wounded. The officers were brought to the Parkland Hospital where Dr Williams was on duty. He told Matthew Bannister about his mood as he started his shift that day.
