Tens of thousands of people braved blazing summer heat Sunday to join a march in Hong Kong protesting the jailing of three pro-democracy leaders for their involvement in the 2014 "Umbrella Movement." Last week a Hong Kong court sentenced Joshua Wong, Nathan Law and Alex Chow -- three young organizers of the protests that rocked Hong Kong three years ago -- to jail terms ranging from six to eight months. They were convicted of unlawful assembly after they stormed government property in September 2014, leading to the 79-day sit-in of major roads in the heart of the city's financial district.
