Not only is there some debate as to whether there is more to the Oklahoma incident than a simple suicide, but explosives have also been found at Georgia Tech and UCLA. Does this look like a trend? These seem to be minor incidents for the most part, and I hope these are totally unrelated, isolated incidents, but I also hope that experts are investigating all of these thoroughly.
