RELIABLE SOURCES? Little Green Footballs characterizes a Debka report of an Osama sighting "in the wildest, most inhospitable regions of Saudi Arabia, the Rub al Khali, the Empty Quarter of the Arabian Peninsula, and Najran on the Yemen frontier." This area of the world is 220,000 square miles (a bit smaller than Texas) and mostly undeveloped. This time of year, it also gets cool quickly after sunset. I have no doubt that US intelligence reads Debka. If the information is true, and goes un-acted upon, that is not good. If the information is true, isn't this an easier haystack to sift through than the mountains of Afghanistan?
