Did an officer actually see this, or is this just another bit of false information being disseminated? Let's see video identifing officers, describing exactly what they encountered when they entered the building.
Exactly. It took X minutes to call 911, the police arrived 20 minutes after the call, it took X minutes to get the cops organized in the parking lot and into the school, and then X minutes to find Lanza. Let us say 30 minutes from start to finish at the very least. With a big bad military assault weapon in the close confined areas of the two rooms and the front hallway he could have done much, much more carnage in that time. With half an hour, he could have gone through the entire school so what else was going on in that half hour?
