Maybe when they found Lanza dead, with the guns, they knew they didn't have to look for the killer any longer and were just checking rooms by looking into them, and not looking in closets?
Not likely...the point I'm making is that these sweeps are thorough...so thorough that they did it 4 times. Here's what Wikipedia describes:
Newtown police dispatch first requested officers on the scene at 9:35 amConnecticut State Police received the first call at 9:41 am, and with Newtown police, quickly mobilized local police dog andpolice tactical units, a bomb squad, and a state police helicopter.
Police locked down the school and began evacuating the survivors room by room, escorting groups of students and adults away from the school. They swept the school for additional shooters at least four times. No shots were fired by the authorities.According to a transcript of police radio traffic, Lanza committed suicide within fifteen minutes of the first 9-1-1 emergency call being received.
They were specifically searching for a shooter (as they should, since they have no idea what went down yet). They were also escorting children and adults out.
Now, first off, schools are not exactly mazes. Especially not this one, I've seen the layout and it's not complicated in any way. I trust the trained SWAT/police team(s) that went through 4 times did a thorough job; that's what they're trained to do. They were searching for a shooter as well as escorting folks out.
I still don't see how or why they continually skipped this closet.
Also, in response to Cairenn's last reply, which was:
"They would have most likely been careful with any place a child might have been hidden. Guys in SWAT gear would easily terrify a child that was hiding."
So they're worried about terrifying a child? With a possible shooter in the building, and children still possibly hidden, they will avoid locked doors because they don't want to scare children? So then maybe they shouldn't have been in there at all. I mean, part of the reason they were in there was to evacuate the building of children and adults.
