Beware this slippery slope!
Criminal or even harsh civil procedural provisions can be used from both sides. Al Gore and his followers would not hesitate to imprison scientists who disagreed with them.
The way to uphold scientific standards of searching for the truth is to control the money and come down harshly on entire institutions that harbor even one fraudulent scientific investigator.
Justice in the military is often meted out to entire units and not individuals. If one member of a unit fails or violates the code, the entire unit is punished.
So it must be with centers of science; let one principle researcher be convicted of fraud and punish the entire center. Then watch how science center leaders climb all over every research project to save their own hides. The peer review process would once again become a serious endeavor, (my apologies to the thousands upon thousands of scientists and researchers who take their profession seriously and already act to uphold the highest scientific standards).
