From the actual article linked to by the submitted post: "Schwartz saw the error in the announcement timing as more than a technicality, citing the false assertion of Police Chief Paul Walters that motorists would be given 4.4 seconds of yellow time at enforced intersections. Records show that seventeen of the city’s eighteen camera intersections had yellow times of 4.0 seconds or less. The vast majority of red light tickets in the city were mailed to vehicle accused of entering an intersection less than half-a-second after the light had turned red." And again, yellow doesn't mean stop. It means "stop if it's safe". If yellow meant unequivocally stop, then everyone would be slamming on the brakes - a recipe for accidents.
