IRA draws a line under McCartney murder

That’s what commentator Malachi O’Doherty told Slugger the day its last statement was released. This latest statment seems to be of a piece with that analysis:

The IRA has spelt out its position in relation to the killing of Robert McCartney. It was wrong, it was murder, it was a crime. But it was not carried out by the IRA, nor was it carried out on behalf of the IRA. The IRA moved quickly to deal with those involved. We have tried to assist in whatever way we can. Unfortunately, it would appear that no matter what we do it will never be enough for some.

The crime is unresolved, and may remain so as long as the Republican movement witholds consent for the PSNI to come into their areas to actively investigate the crime.

Does this mean that the case is effectly closed?
