layers of non-truths

so, in light of the fact that we're reading hey nostradumus! and there's a school shooting in the book, i thought i would take a look at the columbine shooting, and see if i could find two different representations of it. like, if there were conspiracy sites about it that offer different information and/or pictures of the event. while searching the internet i found a webpage (http://www.hardylaw.net/Truth_About_Bowling.html) that doesn't directly talk about the shootings, it goes through and proves why michael moore's documentary (bowling for columbine) was really more of a fabrication than an actual documentary. this caught my attention because people, i included, had watching this movie thinking that they were learning real facts about the causes of and things that contributed to the massacre. but, if david hardy is to be believed, it appears that everyone was just being fed more lies. moore took sections from varying points of interveiws and strung them together to make them appear as one coherent connected paragraph or idea. an idea that served his purpose and helped prove his point. he even combines lines from different interviews to do this. at one point in the movie one of these quotes was from an interview with charleton heston a year after the shooting and heston wasn't even talking about the shooting. throughout what hardy says there are countless more exapmles of ways in which moore intentionally misleads the audience and creates fasle information so that viewers will take his side of things.
i just thought it was so interesting that even one of the alternative sources for information on this subject, one that seems credible, might just be something else that feeds us propaganda. now i really want to look into what hardy says to find out if it's true.
where do you learn real things anymore???
