Hundreds of demonstrators marched against racism, police brutality, and racial profiling in downtown Cleveland on Sunday, where the Republican National Convention is set to take place this week. Police wouldn't let the protesters pass through its security zone outside the convention's location, Quick Loans Arena. The security area was determined and deployed by secret services on Friday, three days ahead of the RNC. The only remaining candidate of the Republican Party, Donald Trump, is expected to be proclaimed the official nominee for the presidential elections, taking place on November 9, 2016.
