People light candles prior to silent march in memory of a teenager, who apparently choked to death while trying to swallow a drug packet as narcotics officers tried to stop him, in Legionowo, Poland, Sunday, March 22, 2015. The death this month of the 19-year-old, identified only as Rafal E., in line with Poland's privacy law, sparked rioting that left several people injured and more than twenty detained.
