No-fly blacklist snares political activists: ‘A federal “No Fly” list, intended to keep terrorists from boarding planes, is snaring peace activists at San Francisco International and other U. S. airports, triggering complaints that civil liberties are being trampled.

…Federal law enforcement officials deny targeting dissidents. They suggested that the activists were stopped not because their names are on the list, but because their names resemble those of suspected criminals or terrorists.’ SF Chronicle
