That DHS spent two years in Sandy Hook running training drills http://www.ct.gov/demhs/ical/eventDetail_page.asp?date_ID=CBC7CBCBCC83CDC9CC might be widely known here but I, being behind the curve, just learned about it at
http://beforeitsnews.com/conspiracy-theories/2012/12/what-was-dhs-doing-in-shady-hook-false-flag-two-years-in-the-making-or-department-of-homeland-security-fail-2446904.html
There are two Sandy Hook scenarios suggested there. False flag is one and another disastrous DHS program is the other. At this point it’s a coin toss.
Based on their history, I’m leaning towards ‘another disastrous DHS program’ explanation although I don’t understand the practicing to fail idea presented at beforeitsnews.
I do think it’s safe to say it’s not likely DHS will get the coordinating right, either.
Nor try to make it any less painful.
