I guess I just fall into the "possible conspiracy nut" catagory, in my thinking about all the shootings that we have had over the last 10 years or so. Most of the shooters have been on some mind-altering prescription medication, and some have been involved in schools where they have mind control experiments.
There have been people with guns in their house for self-protection for years and years, but until the Prozac-related drugs came out, we really didnt have these mindless shootings.
I think they happen one of two ways. First, is the drugged, or mind-controlled person who shoots, and doesnt really even remember what he has done afterwards. They are usually dead afterwards, or in a coma, or some similar state where they can never really tell their story.
The second shooters, are ones where a trained team is sent in to wipe out certain people, and make it look random, as in the recent Navy yard shootings. When those happen, the first reports always describe professional shooters, at least 2, sometimes more, but only one is found afterwards, usually dead, and not a professional shooter, just a deranged person, said to be a loner, and used to be a great person, but now is a mental case.
Another strange thing that I have read about, is that when these shootings happen, there is also a staged DRILL for the same event going on close by. I was listening to the scanner during the Boston Bombing, and there was a drill at the library,and bombs going off there as well. There were also several other bombs found and disarmed by the Boston police bomb squad, so there had to be more involved than just two Russian boys with backpacks.
The stories often seem to change as they progress, from first witnesses seeing several shooters, to eventually deciding it was one lone shooter with an assault weapon, in the case of shootings, and even the pictures of the bombs going off in Boston seems to show windows blowing out rather than in.
Since only about 6 large corporations own all of our news outlets, we seem to get pretty much one official story from all of them, and the only place to find anything different is on some of the little Internet forums and webpages.
