Wingedharpy "Does the end ever justify the means?" Yes, 100% it does.
It doesn't always justify the means but sometimes it does.
If Sian had been kidnapped and was alive and the officer put finding her, and her safety, over following a procedure set out to protect possible suspects, then he would be a hero.
If when the killer said "Want to see another one?" He had meant another woman who I have kidnapped, and had lead the officer to a woman still alive, he would be a hero.
If PACE puts the 'protection' of a possible criminal over the safety of a kidnapped woman then it absolutely is a loop hole, IMHO.

I think he absolutely did what he should have done.
