Conspiracy theorists spend weeks combing through news reports and accounts to find real or perceived inconsistencies and cite those as "evidence" of a conspiracy. Though the board wisely chose not to dignify Halbig's questions with a response, others have assembled detailed, referenced responses answering his questions and debunking his claims.
The simple, undeniable fact is that the children killed in Newtown are gone, and they are not coming back. The Sandy Hook conspiracists would have us believe that the parents and families of the murdered children are part of some sinister scheme or "false flag" event to take away America's gun rights, and that the "dead" children are really alive, presumably to be kept hidden away somewhere for the rest of their lives, or given false identities, or even killed by the government or abducted by aliens who crashed in Roswell and then escaped from Area 51. In the absence of evidence, one wild theory is as good as the next.
Harassment By Conspiracy Theorists The First Amendment to the U.S. Constitution guarantees freedom of speech, and conspiracy promoters take full advantage of it. They are permitted to spread their claims in blogs, books, magazines, television shows and anywhere else they like, including public meetings. However conspiracy theorists typically do not want merely to have their ideas heard; they want them widely accepted as truth. They feel that they have an inside look at what really happened, and become angry and frustrated when they are unable to provide convincing evidence of their claims.
