Given how he fudged the 100,000 tests a day stat, it'll be interesting to see how he manages this.I think I don't believe that. https://www.thetimes.co.uk/article/rising-seas-threaten-nearly-half-of-uks-beaches-cw8mcmxr6 makes me think there's over 3200 miles of beaches (edit: because that's only sandy ones). https://www.gov.uk/government/statistics/police-workforce-england-and-wales-31-march-2019 and https://www.statista.com/statistics/877540/leading-police-forces-by-officer-numbers-in-the-uk/ makes me think there's about 126'000 frontline police.
So even if evenly distributed and they've no other work, can 4 officers close each mile of beach? It's shoot and Hancock must know it.
Maybe a police officer will visit every beach in the country and say "I do declare this beach closed".
Not all on the same day, of course. That would be silly, even for a very long-legged policeman it would take ages.
Maybe they can tender it out to the private sector. How much do you think Serco could charge to do nothing and fall back on the coastline paradox?
What's an impressive corporate-sounding way to say "as coastlines are fractal they have no definable length"?
