Even if he does not serve any actual jail time, I think the punishment is fitting.
1. Felony conviction on his record
2. Loss of medical license and since he does not have a history of medical research doubtful he could even get a lab job.
3. Going to have the snot sued out of him by practically everyone for the next 100 years
His life will be a bit on the crappy side. My only concern is that I want safeguards in place to prevent him from making any profit from this case.
