WESTERN democracies, including our own, are grappling with the question of how to respond to potential terrorism while protecting civil liberties. The word "potential" is key here in that the response to actual terrorist action is the same as to any other serious crime: police interdiction followed by judicial process. The potential terrorism threat is that posed by young men (and some women) who have left the country to fight in Syria or Iraq or Yemen and then propose to return home.
The response to actual terrorism in the United States after 9/11 was the Patriot Act, passed without its having been read by the majority of legislators, granting sweeping powers to the government to collect intelligence and pointing America's surveillance apparatus at its own citizens. This paved the way for legitimisation of torture and illegal detention of suspects.
When, in response to the two massacres in France, it was suggested that similar laws be enacted there, the reaction by senior officials like Dominique de Villepin, the former French Prime Minister, was to warn against such extraordinary measures as not only ineffective, but having contributed to America's losing its moral compass.
Fear of a second 9/11 was used to rationalise the surveillance on citizens, the torture of detainee suspects, the war in Iraq. Those immense failures have not procured safety but instead contributed to further the possibilities of terrorism and thereby to enhance the cycle of fear and its consequences.
We need not be rushed by a yet incalculable risk and fear into creating measures limiting the freedoms of all our citizens. Especially as there is another way of dealing with the risk posed by returning suspected jihadists, one that is well within the bounds of civil rights. That is to treat the risk the same as any public health hazard.
