The transformation of this murdering thug into a peacemaker was not due to some Damascene conversion. The IRA had been so heavily infiltrated by the British - some even thought McGuinness was an MI6 mole - and its funds were drying up as support fell in the US that McGuinness thought  peace might be a good alternative to arrest. He was no Mandela as so many of his apologists claim.

The real architect of peace in NI was John Hume, the Catholic leader of the SDLP who believed in, and fought for, the peaceful reform that was needed in NI and which could have been achieved without the carnage. 

McGuinness's legacy is the RC and Protestant gangs who control drugs, protection rackets and money-laundering in NI.
