From the Economist:
“THEY hate our freedoms.” So said George Bush in a speech to the American Congress shortly after the attacks on America in September 2001. But how well, at home, have America and the other Western democracies defended those precious freedoms during the “war on terror”?
…
Governments argue that desperate times demand such remedies. They face a murderous new enemy who lurks in the shadows, will stop at nothing and seeks chemical, biological and nuclear weapons. This renders the old rules and freedoms out of date. Besides, does not international humanitarian law provide for the suspension of certain liberties “in times of a public emergency that threatens the life of the nation”?
There is great force in this argument. There is, alas, always force in such arguments. This is how governments through the ages have justified grabbing repressive new powers.
…
When liberals put the case for civil liberties, they sometimes claim that obnoxious measures do not help the fight against terrorism anyway. The Economist is liberal but disagrees. We accept that letting secret policemen spy on citizens, detain them without trial and use torture to extract information makes it easier to foil terrorist plots. To eschew such tools is to fight terrorism with one hand tied behind your back. But that—with one hand tied behind their back—is precisely how democracies ought to fight terrorism.
…
Human rights are part of what it means to be civilised. Locking up suspected terrorists—and why not potential murderers, rapists and paedophiles, too?—before they commit crimes would probably make society safer. Dozens of plots may have been foiled and thousands of lives saved as a result of some of the unsavoury practices now being employed in the name of fighting terrorism. Dropping such practices in order to preserve freedom may cost many lives. So be it.
