People like you crack me up. This is a very informative article chock full of forthcoming details, and you have to immediately imply that authorities are hiding something. [yawn]
Actually, I am implying that the Johnstown authorities are being very informative, as authorities usually are, early on.
Later the feds and the media will have some explanation why it was just an 'isolated incident' and we don't need to worry about it. See, for example, the El Al reservation counter shooting at LAX.
