How tough should the police be in enforcing lockdown exercising?

There have been numerous reports of the police seemingly being heavy-handed in enforcing the rules about what people can or cannot do when they are engaged in their daily government-approved exercise. First of all, I think the police have been put in a difficult position. Especially when it's hot and sunny the Lockdown Population desperately want to emerge from their confinement and snatch a little of the life they once enjoyed freely and without Big Brother watching. The police are empowered to make sure that when they do they don't do in vast numbers, they don't mingle and ignore the 2-metre social distancing edict and, it seems, above all, they keep moving wherever they are going, and don't stop for long chats, or sunbathe or picnic or just lie around. It's the keep-moving bit that worries me. After nearly four weeks of this no-life hibernation, is it so wrong and against the law to sit on a park bench with your book and bottle of water for half an hour and gaze at the sun occasionally? If everyone did it on the same park bench, I guess that's a problem. But if the bench is in the middle of a park and no one else is either walking by or demanding to sit next to you to unfurl their sandwiches, wouldn't it be a case of over-enthusiasm if the police ordered you to move on? Yes in my view, but it's going on all the time. Let me record what I witnessed this morning in Richmond Park. For those who haven't enjoyed this wondrous park, it's huge and full of deer grazing, offering plenty of room for lots of people to walk without going anywhere near anyone else. This morning a young Mum was battling with a kite in the strong wind, with her little daughter excitedly watching her. It was a gentle, warming sight. But then to my astonishment a police patrol car which was being driven along the empty road in the park suddenly veered off the road and came heading for the Mum and child, bumping over the grass and pulling up within two metres or so from the kite-flying lovelies. I wasn't close enough to hear what the police officer in the passenger seat said through his open window but I have absolutely no doubt that the one-way conversation would have gone something ike this: "Madam, you are flying a kite. Flying a kite is not allowed under section 78 of the 2020 Coronavirus Act. It is not exercise. It's what we call enjoying yourself and being nice to your kid. That is also not allowed. You will have to pack up your kite and go home. Now." The patrol car moved off and headed for a couple sitting on two fold-up chairs and watching a gathering of deer under a tree. The Mum duly packed up her kite, grabbed her daughter's hand and walked off towards the nearest park gate. By now the said police patrol car, doing its off-road manoeuvres, had stopped in front of the couple in their garden-type chairs. I was far too far away to overhear the dialogue. But, again, it's not too difficult to guess: "Sir, Madam, you are sitting down in chairs. My colleague and I have noticed that you have not moved in the last five minutes. You are therefore in breach of the guidelines set by the government in accordance with Section 49 of the 2020 Coronavirus Act. The guidelines say exercise means exercise which means you have to exercise for an hour and no more. You are not exercising, you are sitting down and watching deer. That is not exercise. You must move immediately." The police patrol car reversed and headed up a path normally preserved for walkers, deer and ducks. The couple hastily folded up their chairs and left. What they were saying under their breath will never be known. I have a confession to make. During these two incidents I stood still, without moving either leg or even arm for at least five minutes, so astonished was I at the state we are now all in where the simplest pleasures in life such as flying a kite with your child or sitting with your spouse for a few minutes to watch a bit of animal nature are BANNED. As for my outrageous breach, stopping momentarily in my tracks which I'm sure is also a serious violation of some section or other of the said Act, please don't tell anyone in uniform.
