Imagine if a government-funded scientist told you that he had the technology to raise someone from the dead. He recorded an apparent resurrection on video, to demonstrate proof of his claims and justify continuing funding. He had a death certificate which was signed by a doctor (also government-funded), and the doctor indeed agreed that the man had been dead.
The video was the subject of much controversy due to discrepancies, the doctor accused of fraud, etc. so to demonstrate that his first resurrection was legitimate, the people provided the scientist with a corpse, and asked him to perform another resurrection. But the scientist, instead of performing the miraculous feat again, simply says, "I destroyed the technology because there was no profit in it. I just counted the cost and quit."
My question is, why should NASA be treated any different to the fraudulent scientist?
