He writes in his column for telepolis.de:
Take, for example, America's proposed CAPPS II, a law which represents a
scary example of the extent to which a government seeks control. According to
this law, all airline passengers would be screened and their records would be checked against the FBI's NCIC (National Crime Information Center) database -- which, ironically, is exempt from requirements to ensure that its contents are accurate.
This means in short, that they can take all data or hold persons which may or may not be guilty, because there is no sort of verification necessary. This is a new high in government observation and an addition extension of the Big Brother state.
Most likely, you cannot even get the information about the criteria via the "Freedom of Information Act" (which is not nearly as free as you think), because those data would fall under national security. Incidentially, those are listed under a category which is exempt from this Act. Tragical and pure luck, isn't it....
