In your mind, I'm sure that's true. But a couple of the inconsistencies ain't trivial.
Which ones?
1) #8 Why did SOI1 not stop them when they went to rape the woman? This reads like he knew what was going to happen. Perhaps it is just written poorly and he only learned their real intent after the fact. As written, it reflects badly on SOI1.
2) You had a question as to why SOI1 let them take his M4. The four soldiers left with 4 weapons (3 - M4's and a shotgun). So this means that one of them left SOI1 with their weapon. So SOI1 is probably well armed.
3) #8 implies that all four burned their clothes. But given that SOI2 and SOI3 allegedly did 'nothing' at the event - why would they have blood on their clothes? This is probably just poorly written. Based on the stated conduct, I would expect that only GREEN and KP1 would need to burn their clothes.
4) #8 says that when confronted by SOI4 as to "Who did it?" he said "everyone who was there". So why is SOI2 are SOI3 listed as 'sources of information' and not as 'known participants' KP2 and KP3? They certiainly engaged in conduct that is actionable - and by their own signed sworn statements.
5) #9 why did SOI2 not put a stop to the plot at that point? Why did he go if he did not participate in the rape? Why did he change clothes? Why did SOI3 go with them?
6) #10 is flaky. First it is KP1 who threw the woman to the ground and then it is SOI3. Since SOI3 is guarding the door, it is likely just a typo. It is not a minor point as it relates to how involved SOI3 was in the crime.
7) #10 and #11. Those are some rough guys to want to have sex just after they killed a three people.
8) #11. SOI3 gives some damning evidence against himself here. Notice that while SOI2 said the woman had been thrown to the ground, SOI3 does not say anything about that. Perhaps because he was guilty of doing that. Perhaps because he was not in the room til the gunshots happened.
9) It can't be much fun mounting guard duty while two guys have their fun. How much time did that take?
10) #12. Whoops. The date error you spotted is there.
Also a typo as 'soldiers' is spelt 'solders'.
