Government are only going to put police out for public order and safeguarding property. They dgaf about hungry children or they would have directed resource at it already.
I'm not out cycling myself and agree it is sensible to limit your riding and follow guidelines if you do head out.
I'm pretty convinced the very small number of people who are out on longer rides are causing very little onwards transmission, and policing it is a waste of time though.
Maybe a better use of police time would be helping get food to the 800k kids who are missing out on their free school meals.
