In the light of the Saville Inquiry report, David Cameron, on behalf of Parliament and the country, apologised to the families of those unjustifiably killed by the Army on Bloody Sunday.
At the time of declaring their ceasefires, loyalist paramilitaries - although not accepted by all - expressed abject remorse for those innocents killed by them during the Troubles.
Surely now is the time for the republican movement, as a gesture of reconciliation, to apologise for the murders they committed.
Like the deaths on Bloody Sunday, nothing justified the taking of one life in relation to a political struggle in Northern Ireland.
The world waited for Mr Cameron to express his regret. Now it's the turn of the republican movement to make clear their regret. If this were to happen, maybe this country could begin to heal itself - but maybe there are still those who don't want that healing to begin.
