The problem is that Britain's laws in this matter are not framed properly. Instead, if the physicians at the hospital would face murder charges if there was even an 0.001% chance that the baby's life would be saved by treatment in the U.S., and they hindered the parents taking the baby there, and thus the baby died... then this whole thing would not have happened.

And the burden of proof that the treatment would not have had any chance at all of saving the baby should fall on the accused, since the basic legal principle of innocent until proven guilty is satisfied by the burden of proof being on the prosecution that they had hindered the parents taking the baby for the experimental treatment.

Always err on the side of life, because we aren't able to resurrect the dead.
