Labeling something "conspiracy theory" is not helpful or descriptive. It only serves to intimidate people gathering information and to reinforce those who feel they are above any fringe theory and/or don't want to leave their comfort zones. Clearly there are those who are putting out disinformation in the general public, just as the government does. One must use principles of logic and research to reach the most likely conclusion. If we are speaking of the Boston incident, we are still in the information-gathering stage and perhaps moving into the hypothesis-forming stage. We aren't ready to automatically throw out premises without investigation.
