Yes, it's high profile. But it's not as if they are being investigated for any of the deaths caused by welfare cuts, immigration policy or the handling of the pandemic. It's a retrospective investigation into breaches of lockdown regulations. Offences for which the Police had powers to issue fixed penalty fines. Powers they were given based on the expectation that commonly they would be used in situations where the filth caught you in the act or soon enough afterwards that it was obvious what had been happening.
The recipients of these questionnaires are obviously lawyered up and so are the filth. Even if the Met are only going through the motions these questionnaires can only be the first step. In reality whoever drew the short straw to head this investigation will be making best efforts to cover their arse in a situation where, whatever the outcome, they can reasonably expect to get it kicked.
I've seen people talking about how the questionnaire process permits collusion but some of those involved in the 'parties' no longer work at Downing Street; some of those left on bad terms; and some have evidently already 'grassed' and supplied photo's and documents. I doubt any of them could realistically count on everyone else at a given 'event', even if many of them weren't fucking weasels to begin with. Anyone who does put their hands up to get it over with as quickly and inexpensively as possible - and I expect there will be some - will hand leverage to the filth in respect of anyone the filth know was at the same gathering. I suspect admissions have already been made to Gray. If some people challenge fines issued the process could drag on for a long time. And so on and so on.
In short whatever transpires - or doesn't - I expect to be able derive entertainment from it.
What I don't understand are demands for more visible 'performative policing' given that it's 'us' who are normally the recipients of that sort of thing.
