The WTS/JWorg likes to convey the impression publicly that they are law abiding citizens who obey the law. This is a fallacy - they only obey the law if and when that law agrees with their objectives. And only then.
The org issued a letter to elders that gave advice on "how parents can protect their children from the misuse of blood". The letter concludes with this advice to parents:
If a court order is issued despite one's best efforts, continue to ask the physician not to transfuse and to urge that no blood alternative treatments be utilized.
In other words, use the law to demand that no blood alternatives be used, but if things don't go your way in court, continue to defy the law and do things the way that the WTS/Org tells you to behave. Demand no blood alternatives. Always. Stand your ground. Disobey court orders. Demand alternatives.
This court case in Mexico is entirely scripted and directed by the WTS/Org. The JW parent and child are only pawns in the WTS' deadly game. They are only following the WTS directives to demand no blood alternatives.
