Every now and then someone claims they're getting photons to break the speed of light in tunneling experiments. Upon closer analysis, sometimes taking years to come through, it always turns out that the "speed" they were measuring was the same kind as you get when you scan a flashlight or a laser beam on some far away wall (e.g. see this paper).
While the light spot does move faster than light on the wall, there is no signal or energy being tansmitted between the successive positions of the light spot. In other words, all that is happening is that the times of light spot shining at some places A and B are remotely synchronized to be close to each other. E.g. if a beam is turned so quickly that the light spot hits A and B almost simultaneously, then the "speed" of light spot "moving" between A and B would be close to infinite. I would put my bet on the hypethesis that these guys have observed this kind of light-spot effect in disguise.
This group is large and hardly a bunch of amateurs - they wouldn’t remotely take the chance of going public without having gone over their data over and over and over again.
My bet is that it’s shown to be a valid result (will take a while, as duplicating their experiment will be very expensive and time consuming.)
