Did Tone give information to the people who were pointing nuclear missiles at us and ready to sweep across Europe if they thought they could get away with it ( hence the need for the info)? And did he also help those who where bombing and shooting families in the UK?
He did better that that he gave letters of immunity from prosecution to IRA terrorists who were bombing families in the UK.
Check out the Downey case, IRA bomber Downey was arrested and charged with the Hyde park bombings which killed 11 people.
Downey appeared at the Old Bailey for trial but when his Lawyer produced a letter from the Northern Ireland office the trial was stopped and Downey was released and allowed to return to the Irish Republic were his associates in the IRA threw a welcome home party,
These letters were issued secretly by the Blair administration in return for an IRA ceasefire.
Also Blair's war in Iraq ,in who's in interests was he working then ,where is the evidence that he acted in the national interest.
Who were the main beneficiaries of the Iraq war.
At least with Corbyn you know what he stands for, in the event of a Corbyn premiership I don't doubt that the security services will keep an eye on him and if he becomes a threat to the national interest they may have to consider removing him just like they did with Harold Wilson.
