The news that airports/airlines (more on this difference in a bit) may be establishing a data base of security risks sounds Big Brotherish. But, how is it so much different from credit risks and credit reporting data bases? If, for example, private airlines (and the U.S. has only private airlines, not any "public" or "national" airline) wish to check the data bases on their customers, is this not quite similar to checking credit risks and ratings before lending money? There is great danger, to be sure, especially if one's writings and public utterances become entries into a "threat data base." But I see nothing unsurprising in, say, American Airlines expressing more interest in Jim Bell or Tim May, both of whom have written publically about terrorism and "soft targets," and both of whom have written about how to make pipe bombs, than in Marianne Smith, retired school teacher from Peoria. And there is even more danger--even unconstitutionality--in *government involvement* in such data bases. It's unclear from what I've seen if this data base is to be run like the private credit ratings agencies or if it is to have inputs from the FBI, NSA, Interpol, SDECE, etc. Remember, private airlines are just that: private. Surely we do not support laws which limit a private airline from using data it has acquired to decide whom to pay closer attention to. This is the essence of what knowledge is. (So long as none of this is mandatory. If Tim's Pretty Good Airline wishes to not bother screening customers, this should not be illegal. Nor, to my mind, should TPGA be exposed to negligence lawsuits, so long as his policies are clearly spelled out.) I find the notion that one's speeches and Usenet utterances could "harm one's security rating" a distasteful idea, but so long as such security ratings are handled by private players, and used by private players, I see no illegality. (Of course, the major credit reporting agencies--TRW Credit, Equifax, and TransUnion--already collude with the government. They collude to falsify credit ratings, to create identies and histories that never existed when they say they did, and to provide government with data bases for various purposes. Obviously a "TRW Security" function would be at least as corrupt, maybe more so.) --Tim May We got computers, we're tapping phone lines, I know that that ain't allowed. ---------:---------:---------:---------:---------:---------:---------:---- Timothy C.
