I don't see much of a problem with it. People aren't dumb enough to look at it and think that yes, for sure there will be an attack on that day.
If it get's more people to donate blood, which is always in short supply, then it's a good thing.
Besides, people here on ATS, and many other websites spout about the next major cataclismic event all the time. Not much different.
Ofcourse two days before my 28th birthday . I atleast wanted to live until I saw 11/11/2011. That's actually a weird date I can't see
somebody really picking that date for no reason.
The 'fearmongering' of the billboard is to get people to donate blood on a regular basis. How is that a 'reprehensible method of control'? If the
Red Cross and other civilian emergency support services need to get people to donate things like blood, and they are in a blood shortage right now,
then who cares?
