The various terrorist factions in NI are notorious for their activities - think of them as gangs, who also dabble in bombs and politics rather than guerilla fighters.
The victim may have been a drug dealer from a rival gang or he may just have tried to stand up to them (innocent people have been crippled, killed and disappeared for many years now). The vigilantes are very unlikely to have been innocents themselves.
