Quality of evidence required for a successful prosecution: Is it too low?

[etr221]

I’m not sure we are following all the facts here.
Does ALL mail for this person go to this address? I’m not sure it does.
It seems to me that the person has the mail procedure in place, but the link with the information given by the guilty party was this person at this address. Given there is a relationship with this address and this person the mail is sent there. It doesn’t mean that ALL of their mail is sent there.

One of the questions I've had is what is - or was - the relationship between the person (whose name got given) and the address - which from the initial post was a business address (self catering holiday home) of his parents, on which basis it should be nothing to do with him, so it would appear that there is more to be said.
