While it's good he was released, let us hope it was because his captors found a speck of light in their hearts and not because of a payout - this would cause precedents and encourage such people to continue the kidnappings.
The release appears to have been triggered by the release of a key Shi'ite militant and not any payout:
The sudden and dramatic release of Peter Moore has not come entirely out of the blue.
The Americans have only just handed over a key Shi'ite militant, Qais Al-Khaz'ali, to the Iraqi authorities after holding him since 2007.
This is the man the kidnappers always wanted back. They made it clear from the outset they wanted to trade prisoners: Qais and a handful of other Shi'ite militants for the five Britons.
British government policy has always been not to make substantive demands to kidnappers.
The tragedy for most of the British hostages and their families is that Iraq's political reconciliation process has only now reached a point where Qais could be released without appearing to give in to those kidnappers' demands.
