The Economist:

As in the war on terrorism, so in the war on crime: the sharp question is how much risk a society is willing to absorb in order to preserve liberty. Mr Shipler’s conclusion is that America is increasingly prone to give the wrong answer. The premise underpinning its justice system is that it is far worse to convict wrongly than to fail to convict at all. But in its responses to drug-trafficking and organised crime that ideal has been severely weakened.
