It clearly says "end the life of Adam". I know this because my headset by default is crazy loud and when I turn up the volume to full that "whisper" is basically a scream and it is very clear what he says.

Which brings up A LOT of questions about the official story (which already stinks about as bad as it gets)... remember everybody at first (including police) though the suspect was his brother Ryan due to the ID on the body being the only way at the time to identify the body (as the school altercation story involving Adam was retracted as it never happened... nobody at the school knew who Adam was).

I personally feel the man on the police scanner that says "Standby units in front of the school, we're conducting an interior search at this time. End the life of Adam." is the guy they found at the back of the school (in the woods, wearing camo pants and a black jacket which was detained by police as described by on scene witnesses) who's job I feel it was to keep the 2 "operatives" inside (which were both on duty police) up to date about the "other" police presence on scene in real-time... how many and where (keep in mind early responders were lacking at first... the majority of police didn't arrive for ~15 more minutes, at this point they only had a small number of police inside the school and another small group covering the front entrance).

So basically the way I see it from start to end...

There were at least 4 people total involved in this. Adam the patsy, 2 operatives (which are on duty "first responding" police on scene before the shooting), and the lookout/cleaner (which is to pass as a innocent by standard after the fact).

The basic jist of how i see it going down...

The lookout/cleaner arrives at the school before the shooting, he gains access to the school interior (possibly even hours earlier... hes in no rush as he will never be a suspect in the end (see later) so is likely buzzed in legitimately by school employees well before the shooting occurs for a valid reason). His first job is to open the "BACK" door of the school at a scheduled time. At the back of the school is 1 operative (dressed in a black jacket, camo pants & a mask) which is with the patsy Adam, and 2 of the 4 guns tied to this crime in some way (1 of the pistols and the AR). Operate 1 and Adam the patsy make their way into the school via the back entrance which the lookout/cleaner opens for them. The lookout/cleaner then waits by the back door with the patsy Adam, while operative 1 goes and waits outside the first target classroom for his signal (the front door breech).

At the same time operative 2 (also dressed in a black jacket, camo pants & a mask) forces his way into the front entrance of the school using 1 of the 2 remaining weapon (most likely the shotgun due to the entrance door glass being broken even though it was reinforced to withstand bullets). He then uses the pistol to shoot at the administrative staff (including the principle) killing/wounding several people. While this is occurring Operative 1 (hearing the signal) then goes into the first target classroom and using the AR shoots as many of the children as he can, and then moves to the 2nd target classroom and does the same. Meanwhile operative 2 (the one that forces his way through the front door) makes his way through the school to meet up with the other operative, the lookout/cleaner and the patsy in the hallway near the target classrooms.

Operative 1 then takes off his black jacket, camo pants & mask (he is wearing a police uniform under it) and puts it on the patsy Adam. Operative 2 takes off his black jacket, camo pants & mask (which is also wearing a police uniform under it) and gives it to the lookout/cleaner to wear (minus the mask). So now basically you have a complete switch. Adam now looks like op 1, the lookout now looks like op 2 (minus the mask)... as seen by witnesses in the school they assume it's the same person, and the 2 operatives now look like police. OK still with me?

The lookout/cleaner then takes the shotgun (which was only used to blow the front door open... which the cleaner doesn't know as he was at the back entrance at that point) and runs to Adam's mom's parked car and puts it in the trunk (assuming it wasn't needed in the crime and shouldn't be found at the actual scene... he's the cleaner it's his job is to make sure the evidence matches the crime which is what he thought he was doing). He also probably hid some other crucial evidence (such as the 2nd mask) in his own vehicle (as he will not be a suspect... I explain why later). Once the shotgun is in the trunk and all "unexplainable" evidence is "cleaned" the lookout see's the actual first responding police arriving at the scene (faster then anticipated). He then goes on the police scanner telling them that he's already inside and to "Standby units in front of the school, we're conducting an interior search at this time" making them wait at the front entrance (and are lacking manpower to surround the building as of yet). The lookout/cleaner then has to somehow signal the 2 operatives/police inside the school that everything is in place and to complete the final piece which is the death of the patsy. I feel they originally thought they would have time for the lookout/cleaner to physically run/walk back to the back entrance of the school and tell them in person after the "inconsistent" evidence was cleaned... but due to an above average first response time, was forces to do it over the airwaves (which is where the "End the life of Adam" comes in.

The 2 operatives which are now dressed as police still inside the building hear the message knowing the cleaner wasn't able to relay the message in person and that other police are already on scene use one of the pistols (the one that up to this point hadn't been used) to kill the patsy Adam Lanza and make it look somewhat convincing of a suicide. They then run away from the body through the school and act like they haven't been to that area of the school yet, and later meet up/blend in with the mass police presence which arrives a few minutes later.

Meanwhile the lookout/cleaner is just sticking around the general area (as fleeing would be more suspicious then anything), as he has nothing to worry about... the 2 first responding police (the 2 operatives which would be seen as the first police on scene) can vouch for the guy saying he wasn't part of the crime in any way (which is why he was able to be released so quickly).

-The lookout/cleaner drives away with "inconstant" evidence (extra masks, possibly extra gloves...) after being cleared to leave by police due to help from his 2 operative friends.

-The 2 operatives blend into the mass police presence that arrive shortly after and have a believable story to tell up to that point, to the point of even being able to sway/spin initial info due to being their first (which is possibly why originally it was reported to be was his brother Ryan... which would be a good stall tactic (especially since they just said "End the life of Adam" minutes before on the police scanner...)

-The patsy is found dead from apparent suicide dressed the same as the actual killer(s) & the 3 guns used are found with the body as expected (minus the shotgun thing which I honestly thing was an oversight on their part). From an eyewitnesses standpoint everything would "appear" to be correct... A perfect crime... well almost.

Just my 2 cent...
