The Tony Martin case made self defence illegal and decriminalised burglary. At a parole hearing, because Tony Martin said he would do the same again, his parole was denied with the official reason that "People going about their lawful business need to be protected" ergo self defence,is illegal and burglary is a lawful occupation. This from Case Law in the UK

This means this pensioner will be tried for murder and the jury will be required to convict due to case law, as the burglars were about their lawful occupation.

Also if a burglar injures themselves on your property, you can be held liable in any civil case.

If a burglar wants to take your stuff and it is heavy, you may have to assist in carrying it out for them, so they are not injured.
