evidence: Retaining Troubles-era "peace walls" between Catholic and Protestant areas seemed advisable even though the 1998 Good Friday agreement had supposedly ushered in an era of peace and reconciliation. [...] Society and politics are sectarian and dysfunctional. Loyalist and republican paramilitaries still wield control in some communities. Children still tend to go to Catholic or Protestant schools, and families still tend to live in Catholic or Protestant areas. Peace walls still proliferate, especially in Belfast. One at Cupar Way, between the Falls and Shankill, stands 45-feet tall, three times higher than the Berlin Wall, and in place for twice as long. [...] Few would dispute that. But there is no clamour to remove peace walls. Partly it stems from fear of trouble, if not the Troubles. Petrol bombs whizzed over an interface at Lanark Way, dividing the Shankill and Falls, in Easter 2021. "Perhaps it’s best to keep them up because if they came down there might be more ruckus," said Gemma Louise, 30, a mother on the Shankill side.
