Why 80 percent, why not 99 percent? Are you trying to be generous?
Anyhow, where your figure came from?
Is it the figure you quoted came from Taliban, Pakistan army, Pakistan government, Americans, Taliban apologists in journalism, or local guy who met you in grocery shop?
Can you please justify the figures you quoted with source and credibility of that source with reason why you think they are credible … that is, they are on the ground tabulating the figures independent of Taliban and their propaganda so that one can believe their figures as ‘could be right’?
Note: As far as I know, the figures quoted by ‘The Bureau of Investigative Journalism’ probably got tabulated taking into account claims by people on ground and/or people present at the site. There figures are getting respect from most sources who do not believe government figures, and according to their figures, more than 80 percent who got killed by drones were terrorists, not innocent civilians.
