The latest theory: that the suspects in the Boston bombing and MIT shooting were both set up by the government, the massive manhunt to kill them is an attempt to bury the truth the suspects know, and that the real guilty party -- of course -- was the government itself.
The Boston marathon conspiracy theories began with Alex Jones's Infowars and end there, although many others have offered similar views. According to Jones's radio show, Navy SEALs surround the entire cordoned-off area of Boston and are actually running the massive manhunt as a drill, an experiment in martial law.
The key to the Boston marathon conspiracy theory is that "the best kind of pasty [sic] is a dead patsy," and that the Chechen terrorists are not "real, organic Muslim terrorists" but U.S. government sponsored Chechen students. "It's a very low probability" that this is a real terrorist attack, according to Alex Jones's live feed.
Infowars asserts that a major component of the Boston marathon conspiracy theory and the ensuing manhunt was the attempt -- now evidently successful -- to kill the suspects (or patsies) so that "any information [the suspect] could have known about additional accomplices or the numerous private security men that were also walking around the scene of the blast... has now been buried."
The Boston marathon conspiracy, according to Alex Jones, was hatched by the FBI "to get more funding and take more civil liberties." The latest of those supposed successes is the imposition of martial law in Boston. Their evidence, to the extent that they have any at all, is that the Russian father, among others, of the Tsarnaevs believes his sons were set up (although the government considered setting up Navy SEALs up until the last minute):
I learned about the incident from TV. My opinion is: the special services have framed my children, because they are practicing Muslims. Why did they kill Tamerlan? He was supposed to be caught alive. The younger is on the run now. He was a sophomore at a medical school in the U.S. We expected him to come home for vacation. Now I don't know what's going to happen. Tell you once again: I believe special services have framed my children.
InfoWars and Alex Jones also claim relentless media censorship of the Boston marathon conspiracy theory. They claim that Facebook is censoring InfoWars' article that Navy SEALs were being set up to take the fall for the attacks. Alex Jones also claimed that Timothy McVeigh "was set up" for the Oklahoma City Bombing. Think about that for a second and then ignore everything else that Alex Jones has ever said, because he's incoherent and because he's a troublemaker.
