Agreed. There are 10 traffic cams in Moscow:
Idaho 511 Travel Information
because I am quite strange, I have watched the cameras, and between bad angles and glare, fog, other inclement weather, etc., IMO these cameras are not what I would consider high quality, and IMO not sure how useful they might be for details.
Also,
within the perimeter LE has set (north Taylor; south Palouse river dr.; east 95; west arboretum), there is only one ID traffic camera, and that is at 95 & Palouse River. Otherwise, LE is relying on business or personal /home video within that perimeter. That is not to say that LE could not use the other cameras once a vehicle of interest were identified within the perimeter - certainly they could do that and appear to have done that. iMO the way LE did this was very smart.
Imo LE chose that perimeter knowing that in order to get to the 1122 King house, the killer was either 1) already within that perimeter or 2) had to cross into the perimeter across one of those roads. Of course, that does not mean the perp had to drive down those roads - it means they had to at least cross one IMO. There is no other way to access the house. IMO, based on the map, LE chose the smallest but most precise search area possible, and expanded from there.
I would bet LE followed the path of any car that moved within that area that night, and they narrowed down to the white HE - this IMO of course. So IMO the white HE was seen on video within the perimeter and then LE used video to follow the HE after leaving the perimeter which is potentially how they ended up hitting Troy and Kendrick. Of course, if the killer was smart, they checked the traffic cams before setting the route in and out. If they actually took Taylor/Styner, points off for bad travel choices (businesses, bus stops, wider streets, etc.).
IMO If the killer made it to either of the two small town, there were more choices they could use. I liked the trail idea, but that's just me. I will say that IMO if people did see someone on that trail biking, running, etc., they might have been more apt to notice appearance if they were looking for a killer, but the murders hadn't been announced yet, so easy enough to slip back into town and/or go to their own car and leave from outside the perimeter. IMO we're still at needle/haystack, but who knows. I can say that IMO the travel cameras could potentially help ID whether a car that appears to be a white/light HE crossed through, but more than that, less likely. However, the FBI has some lean, mean tech tools, so I hope they're able to narrow down a whole lot more.
Everything above is JMO IMO IMI
