Not sure what you mean about dosen't seem right?
We know the virus spreads more in an enclosed environment, Leicester has both, sweat shops within the textile industry and large families.
As for protests and the beach over crowding, along with street parties, in Eastbourne, Westminster and Brixton, they were outdoor events. So yes, we could see the consequence within the coming weeks of those events, but I reiterate they were outdoors.
Such as there is a reason that pubs are being suggested as better serving within beer gardens/streets, because it lowers the risk, sadly a lesson Leicester does not appear to have learned, albeit, it could be due to unavoidable conditions.
