Via orwellwasright:
The responses in the immediate aftermath of the Boston marathon bombing were predictable: the idea that this may have been a false flag event and the dismissal of such a notion with the derogatory expression “conspiracy theory”. Certainly, there are many who instantly jump to the conclusion that “the government did it” when tragic events such as this occur before waiting for all the evidence to emerge – in the current political climate of seemingly never-ending lies and deception, this knee-jerk reaction is perhaps understandable. Equally, those who dismiss these allegations are right to let the dust settle – new evidence emerges and narratives spin from the wheels of government and media, frequently changing and often contradicting one another.
It came as no surprise to anyone that firebrand radio host Alex Jones was the first to call “false flag”. But perhaps less expected was the manner in which the term itself became something of a meme – Google trends showed a major spike in searches and it even made the mainstream media (although expecting Yahoo News to deal with the subject with even a modicum of accuracy would be optimistic, to say the least).
