It's worse than I thought - leaving your own home is now basically a crime.

STATUTORY INSTRUMENTS

2020 No. 350 PUBLIC HEALTH, ENGLAND

The Health Protection (Coronavirus, Restrictions) (England) Regulations 2020...

6. Restrictions on movement

(1) During the emergency period, no person may leave the place where they are living without reasonable excuse.

In criminal law, "reasonable excuse" can be used as a defence against a crime. So if you smash a car side window for the fun of it, that's clearly a crime. If you see a child or dog suffocating on the back seat on a hot day, you are allowed to smash a side window in order to save its life (OK, that might be "implied permission" but same general idea). So, if you need a "reasonable excuse" to do [something], that [something] is a basically an offence, which is restated in para 9.

The full list of narrowly defined "reasonable excuses" is below.

This is completely over the top. On the basis of (questionable) scientific advice, our government, like most governments, wants to reduced infection rates by restricting person-to-person contacts. Fair enough.

If you jump in your car, whizz round for a bit and then park up and go back inside, you don't come into contact with anybody you are not doing against the general spirit of the legislation, so why the hell is it not a "reasonable excuse"? How is that different - in terms of infection risk - to going for a bicycle ride?

The whole section should be re-written to say that you are only allowed to leave your home and come into contact with anybody else in order to [etc].
