sentences:  Catholic workman Gary Moore was killed in Monkstown in 2000 in another killing attributed to Gregg's unit.In late 2001, Gregg's reign of terror in Rathcoole, where drug dealing, knee-capping and savage beatings were the norm, was challenged by local British Labour Party Councillor Mark Langhammer, who also objected to Gregg's close links to neo-Nazi groups in Great Britain.He called on the Police Service of Northern Ireland (PSNI) to establish an auxiliary police "clinic" on the estate, which had no permanent police building, so that locals concerned about crime could have somewhere to go.
