Peter Robinson managed to tie himself in knots when questioned about the DUP's apparent double standards regarding the party's attitude to paramilitary groups.
And despite his high dudgeon at the perfectly valid question put by a BBC Radio Ulster presenter, any listener to the programme would have been aware of Mr Robinson drawing a distinction between IRA violence and UVF violence.
He appeared to suggest that the UVF had not been as much in breach of its ceasefire as the IRA, citing the alleged abduction of Bobby Tohill as evidence.
This is an astonishing attitude, given the UVF's well-documented involvement in a litany of violent incidents – including murder, bombing and racist attacks – since calling a ceasefire.
Indeed, while the unjustifiable and dangerous activities of republicans can in no way be condoned, it is worth noting that the IRA has made significant progress in terms of decommissioning, while the UVF has not only failed to put weapons beyond use but has suspended contact with General de Chastelain's decommissioning commission.
The truth is that both the IRA and UVF have been engaged in activities which run contrary to the Good Friday Agreement and the spirit of the peace process.
However, walking out of the review or engaging in a hierarchy of violence, will not move us forward.
