some people think they're more important than society as a whole so choose to go for unnecessarily long jaunts, or for multiple sessions, solely because it is not expressly legislated against
Agreed.
The legislation has to be read in conjunction with the government guidance and its ultimate aim: keeping people indoors as much as possible.
There wasn’t time to go over every eventuality when framing the legislation so it isn’t watertight but the message is clear in every broadcast made in the public service announcements; stay at home. I could be going out of the house for some fresh air a lot more by making an essential trip to the shop every single day for one pint of milk but I’m not interested in gaming the system when the stakes are this high.
It’s irresponsible to exploit the inevitable gaps in the rushed legislation when the purpose behind them is both well known and so vital.
Taking advantage of loopholes in this situation doesn’t make you clever, just an arse.
