Some of the risk aversion in threads sends my eyebrows right up across the top of my head.
Risk from incomers. I'm not far from a very popular touristy area in West London. A lot of people have been out and about enjoying it since the beginning of lockdown. Many local cafes have been doing takeaways and food and snacks have been available from the local supermarkets. The benches aren't taped off and are generally occupied, and there are lots of grassy places where people sit. From the parking permits in cars it seems that people have been coming from far and wide to enjoy the open spaces, riverside walks and small towns. But our pavements are narrow, specially where there are queues for the shops, there are narrow alleyways and footpaths and there are a lot of narrow places by the river. There are gates with catches to undo. It's been very busy, specially in the good weather and, although people are good about turning their heads away, many times we pass more like 2 foot apart than 2 metres. Occasionally we brush past each other, specially if we have to avoid children, bicycles, dogs, benches, view-admirers, phone-checkers etc, and sometimes a jogger nips through a small space between walkers. There's a lot of pollen and clouds of midges so people cough and sneeze from time to time. Face coverings are virtually unknown. We have a very high proportion of over 80s. Yet I've heard no hostility to the people who flock here from all over.
You would think after about 6 weeks of such dangerous existence the rates of Covid-19 infection in the area would be very high. They have been among the lowest in London since the end of March.
Schools being entirely safe. There is a local primary that is under the flight path to Heathrow. One day a huge lump of ice fell off a plane and crashed through the roof of the school's hall, demolishing it. Fortunately it wasn't a school day. I think the HT of schools here have a good idea of just how much they can guarantee safety. There are reports in the local paper from time to time of lumps of ice and even frozen bodies falling from planes. It's a real risk, yet thousands of people live here.
