Doubtful. There's been no evidence of false flag, merely allegations.
Well, catching FSB agents planting yet another bomb, without notifying anyone of the alleged 'exercise' is rather compelling evidence, more than a mere allegation surely. Plus the FSB arrested the guy who found the viable bomb up for divulging state secrets.
There were also other incidents that raise red flags, like that time when a parliamentarian announced a building was just blown up in his home town ...
three days before it happened.
It is also that the bombs were blamed on the Chechens, who strongly denied any links to bombs, even though they took no measures to hide themselves for other attacks in the same era (Nord-Ost, Beslan).
Information being sealed by the Duma, prohibiting further investigation and arrests of an independent investigator who later died in Cyprus in a hit and run accident are all grounds for more than reasonable doubt in the official story.
There are also other pieces of evidence that make those bombs strong suspects for actual false flags. There is no smoking gun, no definitive evidence they were indeed the work of the FSB, but the evidence does point that way. Certainly more than saying these are "
allegations" would suggest. I believe I said as much in the post.
