Re presence on the scene: If law enforcement arrived in 3-5 minutes, what did LEO do? Did LEO not enter the school at that time? If not, why not? Anyone killed after that 5 minute mark (maybe 6) could have been spared.
We are told that once the person saw police, he killed himself. If police dispatch #33 documents LEO arrival, why the comment that when seeing police, he killed himself? http://news.nationalpost.com/2012/12/16/gunman-adam-lanza-killed-himself-as-police-closed-in-shot-all-victims-multiple-times/
Re audio: A transcript is not audio.
People were killed. There are questions that I would want answered, were I a relative.
The chase up into the woods took place 3 minutes after the dispatch was made [9:36] and within seconds of arrival at the school [9:39--9:40].
At the same time [9:40] the LEOs were swarming the front entrance. It's right there in the dispatch. There is news video of this with the 9:40 timestamp.
He shot himself 6 minutes later at 9:46.
Re audio: A transcript is not audio.
There is audio at the link if you prefer that. Transcripts backed by audio with timestamps noted are better.
