I know the brits are subjects, and not citizens, but our bill of rights was based upon the rights of englishmen. If this had happened in america, let's see--that would violated the fourth amendment (there was no kind of warrant, then the shed was broken into--unlawful search, then unlawful seizure as the goat was removed from it,) the fifth amendment (lack of due process, then property taken/destroyed without just compensation,) and possible the 7th amendment (right to jury trial when value of roperty exceeds $20.)
I know some would say that this was an awful lot of trouble to go through for a goat. While I do agree that the woman was perhaps a little too attached to her pet, fighting against an unreasonable, and unlawful authority for WHATEVER reason is laudable!
