How he is acting right there as the blast goes off though isn't how I would expect someone who is security to be acting though.
You need to ‘go on a mission’ and see what is out there on line to do with the “roof guy”.....and dig til you are relatively satisfied with what there is about him. Then report it back here....so we can eliminate him or consider him.
BTW....Russia and Israel both have their top people helping with this case....In Moscow via the embassays and otherwise.
The fact the father is suposedly in Moscow getting medical treatment is interesting. But I think both Russia and US Investigators likely orchestrated the Moscow trip. They don’t want anything to happpen to him.
Putin’s an interesting character in play as well....not to be trusted but interesting none the less.
