They really had very little choice given that the Coroner prohibited them from returning a verdict that they may have wanted to. It appears the Coroner was under a good deal of pressure from the legal teams representing the police to disallow a verdict of unlawful killing.
I wasn't in the courtroom, I don't have all the facts, but it seems outrageous to me that an independent figure is either pressured into or makes the decision off their own back to make this ruling. It kind of makes the whole exercise a pointless one. Given the information that has come out it would seem reasonable to suggest that the jury would have returned that very verdict they were forbidden from passing.
So the list gets a little longer:
Arrest of opposition MPs
Collection of communications data for all
Entry of all citizens onto a DNA database
The right of entry without a warrant
Systematic and obtrusive surveillance
The right of long-term detention without charge
The right to arrest and detain without detailing the evidence against the individual
The right to stop and search for no apparent reason
The right to imprison those who cannot/will not provide ID on request
The removal of habeas corpus
The extradition of citizens to a third country without prima facie evidence
The removal of the right to trial by jury
The gagging of juries where they exist
The removal of the right to protest outside Parliament
The arrest of dissenters at political rallies under anti-terror laws
And the truth is, there is something terribly wrong with this country, isn't there? Cruelty and injustice, intolerance and oppression. And where once you had the freedom to object, to think and speak as you saw fit, you now have censors and systems of surveillance coercing your conformity and soliciting your submission. How did this happen? Who's to blame? Well certainly there are those more responsible than others, and they will be held accountable, but again truth be told, if you're looking for the guilty, you need only look into a mirror. I know why you did it. I know you were afraid. Who wouldn't be? War, terror, disease. There were a myriad of problems which conspired to corrupt your reason and rob you of your common sense.
