Safe to walk the streets?

There are numerous newspaper reports repeating this:

De Menezes police 'won't face charges'
THE Crown Prosecution Service has ruled out the possibility of bringing murder or manslaughter charges over the shooting of Jean Charles de Menezes at Stockwell Tube station. The CPS will announce formally on Monday whether or not it will bring charges. On Thursday it was reported that Metropolitan Police Commander Cressida Dick, who was in charge
of firearms operations, and two firearms officers could face manslaughter
charges.
But according to reports today, no individual police officers will
face prosecution and the CPS has ruled out murder or manslaughter
charges after a review of the circumstances surrounding the shooting on July 22 last year. The 27-year-old electrician was shot seven times in the head by
anti-terror officers at the tube station in south London after being mistaken
for a suicide bomber.
Harriet Wistrich, solicitor for the de Menezes family, told the newspaper the family was likely to be "very unhappy" if no officer was prosecuted..

Well, I have to say I'm not too pleased either. These were armed officers who one assumes went through proper training. They were controlled on the ground by a senior firearms officer. Again - one hopes - trained. Supervision came from a very senior officer. They are allowed to be loose on the crowded streets armed with very effective weapons. They recognise no situation where they have to consider innocent bystanders. I spent a large part of my life armed and amongst others similarly equipped. However, I shall no longer feel safe when I see armed police. This incident has proved that, with a following wind and who knows what pressure upon the investigators, they can get away with murder.
