Apparently, last week, when the US authorities asked the French Government to block a few planes and check some passengers based on hints provided by the US, the French Air&Borders Police found a four years old girl, a old chinese woman and a british City yupie. The data provided by the US were (I quote) "so weak that the anti-terrorist units here did not even want to open a file"... I seriously wonder if the threat level in the US is not used as an electoral argument; remember that the electoral campaign starts next 19th january...

UPDATE: this is now confirmed by the FBI itself.
