Even as the terrible events at Sandy Hook were unfolding they were "engaged in a "mock scenario of an active-shooter in a school"

South Brewster Patch, December 18, 2012:

By grim coincidence, even as the terrible events were unfolding in Newtown on Friday morning, the Putnam County Emergency Response Team (“ERT”) happened to be assembled for regular training in Carmel, and team members were at that very moment engaged in a mock scenario of an active-shooter in a school. The ERT is comprised of specially trained and heavily armed officers from the Sheriff’s Office and the Carmel and Kent Police Departments.  When news broke of the Newtown shooting, the Putnam County ERT commander called Newtown Police and offered to have the ERT respond to the Sandy Hook school, but that response was not needed because Connecticut police had already secured the scene.

The July 7 London Tube Bombings:

Peter Power, Managing Director of Visor Consultants, a private firm on contract to the London Metropolitan Police, described in a BBC interview how he had organized and conducted the anti-terror drill, on behalf of an unnamed business client
:
POWER: At half past nine this morning we were actually running an exercise for a company of over a thousand people in London based on simultaneous bombs going off precisely at the railway stations where it happened this morning, so I still have the hairs on the back of my neck standing up right now.

HOST: To get this quite straight, you were running an exercise to see how you would cope with this and it happened while you were running the exercise?

POWER: Precisely ...

9/11 NORAD had drills of jets as weapons:

By Steven Komarow and Tom Squitieri, USA TODAY

WASHINGTON — In the two years before the Sept. 11 attacks, the North American Aerospace Defense Command conducted exercises simulating what the White House says was unimaginable at the time: hijacked airliners used as weapons to crash into targets and cause mass casualties.

One of the imagined targets was the World Trade Center. In another exercise, jets performed a mock shootdown over the Atlantic Ocean of a jet supposedly laden with chemical poisons headed toward a target in the United States. In a third scenario, the target was the Pentagon — but that drill was not run after Defense officials said it was unrealistic, NORAD and Defense officials say. 

How is it, that the ever loving and ever caring state is always just a step behind the bombers and shooters who always get to do their worst before the authorities, who had it all figured out in advance, totally screw up the investigation, coming up after much delay with an official account benefiting from neither a competent judicial inquiry nor a proper forensic investigation?
