I agree with most of what you've said except for the breakout area being on the north side. Should SP have gone that way, he would have been caught on camera.A few observations from a long-time lurker.
1. No need to get all hung up on where the true compass directions are for N, S, E, W, or where the church sits in relation to the highway. None of that matters. Clearly LE used the church itself as the directional reference point. We see in their official reports (see the snippet from ECSO) that the side containing the Porte Cochere is referred to as the South end of the church. That makes the main entrance the West. The kitchen side is the North. The side furthest away from the highway is East. Its been this way from the beginning of the investigation.
2. All the debate about what rooms are on the East hall or the South hall - respectfully we might as well be debating how many chairs will fit in the Sanctuary, for all the relevance it has. Its pretty clear from the documents available to us that the murder happened along the West hall (most likely the foyer area) and that the break-in and break-out occurred at the back of the kitchen on the North side.
I think there is probably a desire for completeness of the map, which I can appreciate. But the East and South (and Sanctuary) are the least important areas of the church in terms of the murder that occurred. JMOO.
