One anonymous person, however, is doing his or her part from allowing the theories to gain a foothold on the Internet, purchasing BostonMarathonConspiracy.com to keep it out of the hands of those who might wish to use it.
"I bought this domain to keep some conspiracy theory kook from owning it," the site's only content reads. "Please keep the victims of the event and their families in your thoughts. Thank you."
As it happens, the theorists had already tried.
The first question asked at the press conference in Boston Monday was from Dan Bidondi, an analyst from Alex Jones's InfoWars, asking if the bombing was staged by the government:
"Why were the loudspeakers telling people in the audience to be calm moments before the bombs went off? Is this another false flag staged attack to take our civil liberties and promote homeland security while sticking their hands down our pants on the streets?"
Although Massachusetts Gov. Deval Patrick quickly dismissed the question, it surely won't be the last.
