The deaths of two female PCs in Manchester yesterday have opened a debate on whether all officers should be armed.

A man's still being questioned about the killing of unarmed Nicola Hughes and Fiona Bone.

And it's emerged 29 year old Dale Cregan was on bail over a fatal shooting three months ago.

But Greater Manchester's Chief Constable Sir Peter Fahy says his force believes "passionately" that police shouldn't carry guns - while the president of the Association of Chief Police Officers, Sir Hugh Orde, thinks weapons could make them more of a target.
