People should go back and read the report, or better yet watch the videos, done by the Dutch for MH17. The amount of information they were able to get from a variety of sources was amazing. In the end, they had cell phone intercepts of those directly involved and their commanders, social media photos that showed the missile launcher movements as well as missing missiles, satellite shots, parts of the missile from wreckage/bodies, paint from the missile on aircraft parts, radar records and a lot more. In this case, I would think the U.S. and its' allies all have that and perhaps much more. I can only imagine the surveillance on Tehran right now. Unless Iran just denies total access to everything, the truth will come out as it did in the MH17 case.
