What then is the purpose of live-capture traps if the only thing you are allowed to do is destroy the live-captured animal, be it mouse or squirrel?

And what exactly is the point of a law that makes it illegal to move a grey squirrel or mouse from one place to another place which is already infested with them anyway? Has anyone ever been prosecuted for releasing their live-captured mouse/squirrel down the road?

And while I'm at it, what exactly does my local council do with the fat dormice (Myoxus glis, formerly known as Glis glis) you have to ask it to come and capture if you get them in your house (living in the UK fat dormouse hot-spot?), which it is apparently allowed neither to kill nor release? Now at least there is some point to that rule, since probably we don't want people introducing fat dormice where they are not.
