Suppose someone lives next door to a mental health care home. One of the resident patients climbs out of the care home and breaks into the neighbour's house. 

Who would be liable for the break-in?

 - The patient (even if severely disabled, eg, not speaking)
 - The care home and its owners
 - The council (which gave planning permission to the care home and ignored prior complaints about the patients)
 - Someone else / nobody
