wouldn't the best way at ending ignorance not be to shut this down with zero advances made but allow the child the experimental treatment so that if it qworks or fails at least we learn something?
The American doctors have said:
* the experimental treatment is unchartered territory
* the treatment would not result in a cure
* the treatment would not extend his life
* at best, the treatment might allow Charlie to smile, and look at objects
There's nothing to be learned from this situation; they already know the outcome.
