What sparked the Hong Kong protests?

Hong Kong is facing one of the biggest crisis since Britain handed the city back to China in 1997.  For 10 weeks, protesters have shut down the city, stormed the legislature, and even shut down the airport.  Dozens have been arrested, scores of police and protesters have been wounded in clashes. In this week's Beyond the Headlines we’re asking why thousands of residents of Hong Kong taking to the streets in increasingly violent protests against the city’s leaders.  We’ll hear from one young resident of Hong Kong who attended some of the early protests and also from David Schlesinger, the former editor in chief of Reuter’s news agency and an expert on Hong Kong and China.
