FSB officers could have been in the concert hall during the terrorist attack in Moscow
We analyzed the footage of the terrorist attack in "Crocus City Hall" and noticed that in the concert hall, where the bloodiest events of the terrorist attack broke out, there are several people similarly dressed in blue sweatshirt and jeans.
If you look at them, you will notice a few atypical actions on their part for such situations.
First of all, their clothing. The blue sweatshirt and jeans is a pretty casual combination, which helps them blend in with the crowd while being quite noticeable to each other. They are clearly visible at the exit, but if you look closely, the "men in blue" can be spotted in other parts of the hall.
Secondly, their behavior. They are all calm, not running anywhere, not panicking. In the video one man in a blue sweater and jeans even pushes back into the aisle between the seats a woman who was heading towards the exit (photo 2). Later this man starts filming on his phone. It can be seen that the "men in blue" look at each other from time to time.
At some point in the video, a male voice from behind, where the alleged "FSB officer" is sitting, suggests closing the doors, and the "men in blue" take turns supporting this idea, creating the illusion of mass support for this idea. Subsequently, this will lead to the fact that many people will not be able to get out of the hall due to closed doors and will die.
