I posted a link to a video which was removed, so Google or search YouTube for Wolfgang Halbig, a school safety expert who wAs involved in the aftermath of Columbine and after looking at Sandy Hook, became concerned. He is a former Miami State Trooper, school principal, and expert on school safety who says the investigators at SH broke multiple well known procedures. He is NOT a CT! He says he was threatened by Conn. officials and that none of his calls or FOI requests have been returned. Why not? I think the questions asked by this former cop and educator deserve to be answered. He's right; the pieces do not fit. Period.
