Computer-Assisted Passenger Prescreening System

The Computer-Assisted Passenger Prescreening System (often abbreviated CAPPS) is a counter-terrorism system in place in the United States air travel industry. The United States Transportation Security Administration (TSA) maintains a watchlist, pursuant to 49 USC ยง 114 (h)(2), of "individuals known to pose, or suspected of posing, a risk of air piracy or terrorism or a threat to airline or passenger safety." The list is used to pre-emptively identify terrorists attempting to buy plane tickets or board planes traveling in the United States, and to mitigate perceived threats.

Famous quotes containing the words passenger and/or system:

    Every American travelling in England gets his own individual sport out of the toy passenger and freight trains and the tiny locomotives, with their faint, indignant, tiny whistle. Especially in western England one wonders how the business of a nation can possibly be carried on by means so insufficient.
    Willa Cather (1876–1947)

    We are now going through a period of demolition. In morals, in social life, in politics, in medicine, and in religion there is a universal upturning of foundations. But the day of reconstruction seems to be looming, and now the grand question is: Are there any sure and universal principles that will evolve a harmonious system in which we shall all agree?
    Catherine E. Beecher (1800–1878)
