Seeing these actual camera angles is informative. Hopefully LE got some helpful video from those feeds, but maybe not. We just don't know. Some notes:
1 Interestingly, we do NOT see the entry point or driveway into the CCOC property, as you note. So if a vehicle came from the Midlothian direction (which would be from the left end of the highway in the picture), they could enter and go to the far side of the property from SWFA (which is where the break-in did occur) without being seen or captured on camera.
2 As you note, the dark and the rain would have added another issue.
3a One other item - on the feed you used, we see a continuous video. But if the cams are motion activated, they may or may not have set up "blackout" areas in the motion detector (to limit the motion activation to what might be relevant to SWFA).
3b During the day, there would be constant traffic on that highway. But in the middle of the night? Not so much.
3c How the cams are set is something the public doesn't know, and would be a significant factor in what they had the potential to capture at CCOC in the far distance. We have to remember that they weren't set up to necessarily capture anything at CCOC.
4 There are also trees between SWFA and CCOC obscuring the view of the cams. If perp turned off headlights when entering the SWFA property, that might have made him "invisible" to those cams.
5 I saw a mention that LE used "an external hard drive" to get a copy of some SWFA video, but the use of an an external hard drive is fairly mundane (and such use doesn't even tell us how much video there was). Those are also called USB flash drives or thumb drives.
6 How much video was there? Those thumb drives come in a variety of capacities from well under 1GB (ie, hundreds of millions of bytes) to multiple TB's (multiple trillions). Videos captures do use a lot of bytes, but we have no way of knowing whether they had hours of actual footage to view and examine, or 15 seconds here and there, in the hours preceding the murder.
The thumb drive(s) for SWFA video can be easily purchased most anywhere. Labeled and kept as evidence for the trial.
SP certainly may have parked behind the Church in the parking lot out of view of the SWFA shop. However, ...
There is a worn path behind Creekside Church that runs alongside Prong Creek. On google earth, if one follows N Prong Creek to the North, you'll eventually see where there is a possible route across Prong Creek and onto land in order to be able to reach the opposite side of the Creek then continue a short ways before turning W to walk on the grass out to the street in the neighborhood.
In the beginning, many years ago, I discussed this escape route, with another person. That is for N Prong Creek, as a possible get away from the property for SP.
N Prong Creek continues on N and is seen as being in the backyards of a few residents. Lawns are fenced off. The small neighborhood is filled with nice large lots. SP is dressed like a cop. He doesn't care! Who would likely see him at 4:45am making a dash for his vehicle?
Missy mentions this particular neighborhood in a FB post when reporting a vehicle accident at the turn in to the neighborhood by complaining it's not the first accident that has occurred at that location or similar wording.
While I'm not sure how long it'd take to walk from the neighborhood to the church via N Prong Creek, I do believe there is time for SP to park his vehicle at the far RT corner of this street and connect with N Prong Creek by walking through the grass.
When departing Creekside Church, the killer could have exited the way he entered then ran through the parking lot in the rain to the path that runs alongside the creek in order to not be seen. SP could be inside his parked vehicle within 20 minutes. And, could have used the creek water to rinse away any bold or outstanding evidence.
This plan is not suitable for a SP wearing one or more Prosthetics.
NPC as Hwy 287 Chris Kyle Memorial Highway goes over it. Snap taken from the SE corner of the parking lot looking toward SFWA
(not pictured).
This 2nd snap is directly across from the NE corner of the Church facing N. Note the two trails in the dirt leading away in the distance.
On the right hand side in the photo is a hand made path that leads to the edge of N Prong Creek; created by a class that's near the creek's edge.
And here's a snap of N Prong Creek flowing in July, 2016
