Momentum is building on social media to boycott the Black Friday sales in order to hit corporate America "where it hurts" over the fatal police shooting of Michael Brown. The Justice for Michael Brown Leadership Coalition is organising the 'No Justice, No Profit' boycott campaign on Thanksgiving Day (27 November), through to Sunday. Black Friday is traditionally the day that kicks off the Christmas buying period with retailers across America offering big discounts to jump-start the busiest shopping days of the year.
