Scientists faking research

This recent March 2006 article in Winnipeg Free press mentions that more than a dozen research scientists were found not only faking research but were also destroying data as well as plagiarizing.
I ask you if scientists are willing to resort to such unethical tactics in order to receive funds for research grants, what is to stop them from also "doctoring " their expense accounts. Probably of more fundamental concern Is the image that they present to the naive and budding scientists- who are their understudies.
Maybe it is time that we also had a "Gomery-type " commission investigating our university profs- items like quality and quantity of research and teaching, their expense accounts, their perks like educational leave, selection for emeritus professorship, etc. etc. etc.
