I am very happy to accept that particular challenge. My amendment may well not be watertight. I understood that there were some reservations in the PSNI about a statute of limitations. That is one of the complexities.
There are other complexities: if we introduce a statute of limitations in Northern Ireland, why not introduce it elsewhere, where the British military is involved in other campaigns? I am sure that we will hear from the Secretary of State about other difficulties involving the European convention on human rights and so on, but the principle is that there should be some form of limitation. We cannot endlessly go back. Are we to reopen cases where it is alleged that Canadian or British troops shot prisoners out of hand in one of the more difficult days after the D-day landing? Should those cases be reopened? Nobody in this House would say yes. There must come a point when we have to draw a line.
