Personally, I'm uneasy with the notion of ending investigations and prosecutions of former British soldiers simply by virtue of them being former British soldiers. If crimes were committed, they need to be dealt with.
I'm sorry but being asked to police a terrorist war in part of your own country with one hand tied behind your back while the opposition killed and maimed many innocents - does not mean British military should be held to a higher level of account when so many of the terrorists were given a free pass.
However, constantly going back over it and opening up old wounds is less than helpful (although that is a national sport in the Province).
