Forget the error in his speech. The local CCTV was not sought. They never actively "knocked on doors and found out who had it" and that is really bad.
The police said that it was a misunderstanding over the CCTV. They were restricting themselves to only collecting Hi res versions of CCTV where more than one view of the same area was available, so I figured where it was said CCTV wasn't collected that they already knew they had that view covered?
I think the police have done a LOT more than most people think they've done from only listening to the family's updates. If you go through the updates on the constabulary webpage for Corrie you can see lots of things going on, plus I read there was a mobile incident room out and that was showing stills from CCTV, and the police were out the week after the disappearance at the same time Corrie disappeared and they were talking to people who were out on the same night at the same time.
I feel like we're not usually privy to even this much detail of an active investigation, and maybe the public is a bit spoiled by TV cases that are solved within the hour, following clue to clue, but in this case they haven't found the clues to follow them, and it's confusing to the public to 'see' this going on for so long when they have in mind other cases that were solved faster. But we've got to be realistic, there are cases of serial killers that weren't solved for years and after multiple victims, and there are people who've been missing for more than ten years with no one knowing what happened to them. Ben Needham and Madeleine McCann are two well-known examples of missing for years, and they were little children who naturally garner wide media attention.
As far as public searches go, it seems to be a case-by-case thing... I do often see that public are involved in searches for missing children in the first few days, but in other cases the police specifically state 'no public searches wanted' and I honestly don't know what makes that difference? I know in a murder inquiry that it's important to not have the public messing up a crime scene, and then add in like difficulties with private property and in the BSE area there's a lot MOD land that the public shouldn't go onto.
The apparent lack of door-to-door inquiries surprises me.
Then there were people complaining that there were police taking away cars in Newmarket one day. It was the day before the Queen visited and they have to do things like that in case one of those cars has a bomb in the boot or someone puts a bomb under one of those cars. But a herd mentality ensues on social media and people will get cues from the family's frustration and confusion but also they will get cues from each other, and right now everything is aimed at the police, and I do think most of that is OTT and based on not understanding just how much the police have been doing and the amount of inter-agency cooperation there has already been.
