Ok I've read a few of the comments, I for one don't care about religion or race...this is about parents wanting the best treatment for their very sick child THATS ALL! If they feel they can achieve this elsewhere then they should have that right regardless.
To be treated in this way (deliberately blocking medical records) can only be seen as malpractice in my eyes, honestly if I were in their shoes I would do the same.
Its clear he has done the research, spoken to other Doctors 'who are trained in the field he wishes to use'. Why then block them and man hunt after threatening of legal responsibility revoke.
