Northern Ireland maintained an uneasy calm a day after Protestant militants killed a Catholic man. "The killing is not being read as a definitive response to the cease-fire," says TIME Dublin reporter Tony Connelly. "A Catholic has been killed once a week or once every two weeks since a long time before the cease-fire." Still, he says, the enmity and distrust between Protestants and Catholics has hardly waned since the declaration of a cease-fire. According to a poll released today in the Irish media, a scant 9 percent of all Protestants in Ireland believe the cease-fire will be permanent. "You can't unravel 25 years of bitterness in a day," says Connelly. "The hard part is just beginning."
