One only needs to visit public hospitals to appreciate the vulnerability of patients, yet it is not something we think about every day.
Security is a concern. Gates are normally wide open and even where they are drawn closed, they are opened without much prompting as vehicles and people approach. There is no pretext of going over people with metal detectors. Where there is a semblance of security, the preoccupation is with patients not leaving the wards without parting with what is due to Caesar.
