The HLC is present to impose the conscience of the GB on the ill JW who
is between the sheets. For "old school" JWs this means helping them
understand what "fractions" they may take.
For JWs who want to exercise their own conscience the HLC's job becomes
the enforcer, policeman or as some medical staffs have observed, they
are the Gestapo of the JW world in the hospital. This Gestapo role is not
without justification to the JW mindset. More than a few JWs will accept
forbidden blood components when out of sight of prying eyes. Why do
you think that JW elders and "strong" family members want someone with
the patient at all times?
