I'm not in DDP but what's to say they died in 2015?
Afghan militant Jalaluddin Haqqani has also probably been dead for quite some time:
Like Mullah Omar, another unique not-hit for someone in the DDP. Looks like someone over there decided to check on a few people (for his deadpooling?) and found a couple of corpses.
I'd bitch about it so best I'm not playing lol.
That said, this is precisely why a DP shouldn't allow terrorists or other highly potential unsubstantiatable folks, which means terrorists :-)
