The Boston Bomb Drill

In the last post, I gave you a quick rundown of the Boston theories Infowars has presented thus far. I deliberately left out their "best evidence", however, because that requires a post all its own. So here it is. 

As you probably know, one of the most popular theories about 9/11, 7/7, and other "false flag events" is that training exercises and emergency drills were deliberately conducted in proximity to the events in order to create confusion, delay emergency response, and provide an excuse for perps to be in the area. Infowars tried to claim that such a drill was carried out just two days before the Norway attacks, but that turned out to be a fluke (the drill was actually conducted over two years earlier).

On the day of the Boston bombings, Infowars and Natural News reported that another of these fake drills was taking place at the marathon, with bomb-sniffing dogs stationed at the start and finish lines. Most damning of all, public announcements were warning the crowds to stay calm before the bombs went off, assuring everyone that any disturbance or increased security presence was merely part of a "training exercise".
Let me rephrase that. It would be damning, if Natural News and Infowars could get their stories to sync and could offer more than a single source of information. NN reported the drill warning was given after the bombs went off, while Infowars reported it was given prior to the explosions. Both reports cite the same source, University of Mobile running coach Alastair Stevenson. It seems the Infowars report might be the more accurate of the two, as another source indicates Stevenson was just returning to the area when the explosions occurred. In this account, Stevenson heard the warnings about a training exercise when he started the race.
The presence of a bomb squad and bomb-sniffing dogs at the start line seems peculiar, especially in light of the fact that the Boston Police Commissioner stated police had “no specific intelligence” there was a drill being conducted that day.
So far, however, Mr. Stevenson is the one and only witness to report seeing bomb-sniffing dogs prior to the bomb blasts. Any story that relies on a single source for its very existence is weak, to say the least.
