Seems to me, these 'Trained' Police negotiators need to go and get 're-Trained'
They failed to take into account, the impact speaking to his wife may have had on this, obviously disturbed individual.
And this isn't the first incident by a long chalk!
Two months ago in Rothbury (near where I live) another crazed Gunman shot himself after Police again failed to allow people who knew him, to attempt to talk him round.
They bandy about 'Public Safety' as an excuse all the time....but with mobile phones and other technology, it's not like these people's family/friends are in any danger.
It sometimes feels to me, like it's more about professional egos, than it is about bringing these incidents to a peaceful conclusion.
