Let's just take a little step back guys, and consider an alternative scenario.

A guy steps into a tube train, followed by a bunch of cops who believe him to be a known terrorist, and further believe that he may be a suicide bomber.

Like good little cops, the call out "Police officers! Stand still!"

BOOM!!!   40 people are dead, including the cops, and another 60 are injured, some permanently.

What do you suppose the survivors would be saying about those cops in court when suing the Met for failing to protect them?

And what would YOU all be saying on here?

Not so black and white as you might think, eh?

The one man responsible for that poor boy's death, was the officer who identified him as the suspect they were observing.
