Last June in Istanbul, Berkin Elvan, then 14, went out to buy bread for his family. He didn't return. Elvan got caught between skirmishing police and anti-government protesters and was hit by a tear gas canister. He slipped into a coma and became a rallying point for those opposed to reigning Turkish Prime Minister Recep Tayyip Erdogan, who has ruled the country for over a decade but faces calls for his resignation amid corruption scandals and mounting public frustration with his heavy-handed governance. When Elvan died this Tuesday, protesters once again took to the streets and clashed with security forces.
