BEIRUT — A dozen Lebanese women, dressed as brides in white wedding dresses stained with fake blood and bandages, gathered Tuesday outside government buildings in Lebanon’s capital to protest a law that allows a rapist to get away with his crime if he marries the survivor. The law, in place since the late 1940s in Lebanon, is currently being discussed in parliament after a lawmaker called for it to be repealed. Standing before a banner that reads: “White won’t cover rape,” the activists are taking advantage of a reinvigorated Lebanese political life following parliament’s election of a president after a two-and-half-year paralysis.
