I think the OP was making the point that regardless of whether this kind of violence involves travellers or not, it seems wrong that Gardaí should be offering to mediate. If laws have been broken then the offenders should be arrested as any ordinary citizen would be. Offering mediation, in my mind, likens the situation to a political one such as Northen Ireland where organisations were justifying their use of violence as a political cause. Riots between feuding families, travellers or otherwise should not be given the same political stance.
