Jimmy Brown was a member of the Irish Republican Socialist Party (IRSP), the Irish National Liberation Army (INLA), and the Irish People's Liberation Organisation (IPLO). Brown left the IRSP in the mid-eighties to join up with the IPLO which then took part in a bloody feud with its former comrades. Brown was gunned down in a dispute between factions of the IPLO. It was ended by the Provisional IRA in 1990. Wikipedia
