Article Photos: Rio police reconsider limit on tear gas at demos 6/6

FILE - In this June 27, 2013 file photo, protesters run from tear gas dispersed by police a few miles from the soccer stadium where Spain and Italy met in a Confederations Cup soccer semifinals' match in Fortaleza, Brazil. Police are debating whether to honor a pledge to cut the use of tear gas against demonstrators, a commander said Thursday, July 18, 2013, after a small protest boiled over into rioting in one of Rio's wealthiest areas just days before a visit by Pope Francis.
