I was working at the home of a recently retired police detective today, and he was very angry about Mackey's cowardice ( his word) , and said that if a junior police officer had acted in that way he would have been hung out to dry.
Plenty of Police Officers ( serving and retired ) are saying that Craig Mackey's refusal to help a fellow officer in danger is inexcusable, and that he should stand down immediately.
I hope the image of poor PC Palmer being stabbed haunts his every waking moment.
