Some food for thought: This is not directed at any one poster, but I see a lot of our theories (some of mine included) are being based heavily on the number of minutes we think occurred between when the neighbor reported hearing two gunshots and when the 911 call was made.
A few issues I see with basing our theories on this time gap:
1. The sheriff has never verified the time the gunshots were reportedly heard (or even mentioned that witnesses heard gunshots). He has said, however, if it didn't come from his podium it is not credible information.
2. The neighbor has contradicted herself on almost every detail except for the number of gunshots-- Was the first one louder or the second? Was she asleep or awake? Did she know they had a child or not? Etc, etc. She may be well-intentioned in reporting it but may still have a faulty memory or be off on the timing, could have read the clock wrong or been overtired at the time. She didn't know she would need to recall the time of hearing gunshots until the next day when the FBI surprised her by coming to her house. Witnesses often get things like this wrong because they had no reason to remember an event or note when it happened.
3. Even if the neighbors' given time of two gunshots heard is accurate, we do not know if that was the beginning of the confrontation, the middle or the end. Even I have made theories based on this and speculated that maybe it took more time than planned to get inside, trying to account for the gap. But that doesn't mean that is how it happened or that they were the first shots at 12:31.
What if we removed those "2 shots heard at 12:31" from the equation? Would our theories change drastically? We are trying to explain a time gap and what could have happened during that gap as if it is a settled fact. That 20 something minute gap may or may not have occurred as reported to us. JMO. Some things I'm thinking about as we rehash what we know and don't know....
