Great news - at last things are changing. There's been series of these incidents for as long as I can remember and the police have always been exonerated. Look up Stephen Waldorf for a horrible tale of 30 years ago.
If a young private on his first tour of Northern Ireland, working in very stressful conditions, shot someone in error he was court marshalled. If the police shoot someone like Harry Stanley, they're not even charged.
A French colleague tells me that their armed police don't have a history of killing people unlike our unarmed officers. How true this is - Inquest can't give me the statistics - I don't know.
Remember PC Dixon was fiction!
