in my opinion, you've answered your own query. Bill could have been apologizing for stealing the weapons and ammo. Besides, in order to discover who the traitor is they kind of need to be alive. Bill doesn't seem like the type to have written down a master plan and left it in a drawer to be discovered later.
Another thing that has been bugging me (now that we've brought up Tommy), is how did the person betray the Tower without alerting the guard on duty? By the way, this question is slightly self serving and leads directly to my accusation of Datu who is good with simple electronics and could have bogarted a radio some how and hooked it up else where in the building to call the Mallers without having to do it from the security office.
