You've mentioned a lot of resources going into searching as opposed to CCTV watching (apparently so).
I think it's about the police assessing a situation and assigning likelihood scenarios. So the most likely scenario would have been a drunken young man trying to walk back to base and coming to an accident by the roadside or in a body of water. Hence a lot of searching along that route from BSE to Honington.
Alongside that, if you follow the official police updates, they've called the local taxi services and asked them if they picked up anyone matching Corrie's description. They figured out the bin lorry. They were looking for the mobile phone pings, and those pings led to Barton Mills mast, which is also where the bin lorry went. So they confiscated the bin lorry and made inquiries at the recycling centre.
Still doing those searches at the same time as other lines of inquiry. At the same time they had been searching Corrie's rooms and quarters, talking to Corrie's family and his workmates and officers. They got information about the phone calls Corrie made/received that day/night and had to interview the people on the other end of the phone about the content of those calls. And at the same time they're picking up CCTV from the area where Corrie was last seen and started to get viewing that.
The line searches in the road. Well if a mobile phone has been run over by a car then you've got to do that formation to look for tiny pieces of plastics and chips from the phone, and the case material. They're not just looking for Corrie lying in a hedgerow after being knocked down by a car, they're also looking for signs of Corrie, his phone, wallet, and key fob. Also his clothing, even just little scraps of it that might have been torn off in bushes. Along the BSE to Honington roads they were probably also looking for fresh tyre marks to indicate someone had swerved suddenly.
My personal explanation is that as the searches have come up empty along the roads/rivers/bodies of water, and the CCTV does suggest to me that Corrie left the horseshoe by the time the running man and the bin lorry were there, that probabilities have to be reassigned, and it turns into "could he have got into a vehicle willingly". But which vehicle? Was one there at the right time but you just can't see Corrie get into the car/van? What do police do in this situation? What about trying to get more evidence from human beings who were in the area? Hence the police pod (and I'm sure that costs enough money and resources that it's not just about the family moaning and the police acquiescing, but about the police thinking it is worthwhile).
And at the same time the pod's up, the CCTV has gone to Scotland Yard for further analysis. They're making inquiries as to whether they can get permission to do a fuller interrogation of the mobile phone mast (RIPA Act) and ten other lines of inquiry that are happening in the background that we're not privy to.
And concurrently with all of this, they've got two murder inquiries and several other missing persons inquiries ongoing.
It's frustrating to me to know the family haven't found their boy yet. But, other than man-hours and financial resources, I think the police appear to be doing a lot on this inquiry, and everything for a good reason.
