I have just received the BAR for Jan/Feb 2012
The following is in her view a summary of four wrong interpretations for different segments of the parable:
1. The robbers were freedom-fighters, dispossessed peasants forced into debt by Roman and Temple taxation, kind of Robin Hood’s of the times
2. The victim deserved his fate as he would have been a tradesman who became unclean as a result of him mingling with all kind of people
3. The Levite and the Priest avoid the victim as a precaution should he die or be already dead; by touching him they would have become unclean.
4. The victim was Samaritan, an outcast (not a real enemy of the Jews as they were in reality)
Her objections for each interpretation and her own explanation can be read in the article using the above link
