Bogside Murals. Revolutionary images of freedom fighters, including the the Petrol bomber mural by Bogside Artists, depicts Paddy Coyle, inspired by a photo by Clive Limpkin shot in the late sixties, when there were lots of running battles, between the Republican Irish kids and the RUC police (Royal Union Constabulary), with molotov cocktails, and CS gas. Around 3,600 people were killed before the 1998 Good Friday Agreement. If a hard Brexit produces a fixed border in Ireland, this peace agreement could be destroyed and the violence could start again.
