Since modern technology allows every fool with an internet connection to broadcast his or her ravings, I would be making too much of the emails if they didn't exemplify a wider culture of denial. It holds that the threat is manufactured, and when exploding bombs or the arrest of alleged bombers shows that it is not, it insists that the 'root cause' must be the behaviour of Western governments rather than the logic of a fascistic ideology.
No, arrests of alleged bombers do
not show the threat is not manufactured. They are the first step of a legal process which, if it works properly, eventually tells us whether there really was a threat. But the things Blair proposed (indefinite detention without trial of foreign suspects, detention for 90 days without charge of British suspects, home arrest without trial of suspects) try to get round that process, and show us nothing - only who the government feels like victimising. Hoffmann would have been right to say "the government was engaged in an unwarranted power grab", but that was actually twisting his words. Here's what he really said, in his ruling on the indefinite detention without trial of foreigners in Belmarsh:
Freedom from arbitrary arrest and detention is a quintessentially British liberty, enjoyed by the inhabitants of this country when most of the population of Europe could be thrown into prison at the whim of their rulers. It was incorporated into the convention in order to entrench the same liberty in countries which had recently been under Nazi occupation. The United Kingdom subscribed to the convention because it set out the rights which British subjects enjoyed under the common law.
...
Of course the government has a duty to protect the lives and property of its citizens. But that is a duty which it owes all the time and which it must discharge without destroying our constitutional freedoms. There may be some nations too fragile or fissiparous to withstand a serious act of violence. But that is not the case in the United Kingdom. When Milton urged the government of his day not to censor the press even in time of civil war, he said: ‘Lords and Commons of England, consider what nation it is whereof ye are, and whereof ye are the governors’.
This is a nation which has been tested in adversity, which has survived physical destruction and catastrophic loss of life. I do not underestimate the ability of fanatical groups of terrorists to kill and destroy, but they do not threaten the life of the nation. Whether we would survive Hitler hung in the balance, but there is no doubt that we shall survive Al-Qa’ida. The Spanish people have not said that what happened in Madrid, hideous crime as it was, threatened the life of their nation. Their legendary pride would not allow it. Terrorist violence, serious as it is, does not threaten our institutions of government or our existence as a civil community.
I said that the power of detention is at present confined to foreigners and I would not like to give the impression that all that was necessary was to extend the power to United Kingdom citizens as well. In my opinion, such a power in any form is not compatible with our constitution. The real threat to the life of the nation, in the sense of a people living in accordance with its traditional laws and political values, comes not from terrorism but from laws such as these. That is the true measure of what terrorism may achieve. It is for Parliament to decide whether to give the terrorists such a victory.”
http://www.publications.parliament.uk/pa/ld200405/ldjudgmt/jd041216/a&oth-5.htmHoffmann was talking about specific attempts by Blair to ignore established British and European law. But Cohen left out the bit about "in the sense of a people living in accordance with its traditional laws and political values" and claimed Hoffmann "allowed no room for argument about the balance between liberty and security".
Cohen was wrong about the Iraq war, and he's even more wrong here. He's smearing his opponents, by tying them to people he describes as "crackpots", "fascists", "raving fools", and he's siding with an authoritarian government, tooling up to get 90 day detention without charge right now. His journey from the left makes him the archetypal British neocon.
