Burglary means forcing entry to a house to steal from it. There HAS to be evidence to bring the charge. Stealing by finding is a crime but it is a long way from burglary which is a far more serious charge.
What evidence is there to support a charge of burglary? There HAS to be evidence of forced entry to the house, and evidence linking the suspect to the scene of crime!
Despite what you say about the police officer 'having it in for him' there MUST have been evidence sufficiently strong for the magistrates to refer the case to crown court. If it was as obvious as you say that the charge was groundless, the magistrates would throw the case out, not send it to Crown. Sending the case to Crown means they consider the case is too serious for their sentencing powers.
I have worked as a tutor inside a prison . I heard stories like this everyday, sorry, but the story you and the BF tell just does not add up!
