lack of evidence / intelligence from a non-credible source ---
if you are actually looking for an explanation then I will be more then happy to share - but if its for trolling then good luck ---
if you can see in both cases Military has not come up with official statement --- all we see in news is "Anonymous Source"
now "Is that source credible enough to trust him with the news" ??
For all I know is that "this Anonymous Source" is some low ranking Sub inspector or staffer, who heard from his friend who is a Traffic Analyst ---- or some guy who sits behind a desk and his job is compile Intelligence reports from multiple sources ---- some of them are good, some are bad---
Now how Intelligence is gathered from Taliban? - mostly its from Radio chatter, Mole (taliban who is on your side) or actually an intelligence personnel sitting among Taliban
In first case it is possible that Chatter must have been heard that he is Injured in drone strike --- or sometime Taliban act smart and try to send in wrong Intelligence - this is Counter Intelligence / Counter Surveillance ----- some guy puts out the word one Taliban is dead ---- when you combine both intel - it adds up that Adnan Rasheed is dead as he was injured----
I hope it makes sense to you now??
word has it - he was injured in first strike ---that is why he had been quiet for a while --- they sent him for some R & R
