Sorry, professor, but you're wrong. The MPC needs to be jettisoned from law schools. It doesn't reflect the reality and some of us do practice criminal law after we leave law school. That's why you're teaching it to us - so that we can eventually practice that which we have been taught.
We had two professors at my law school who taught crimlaw. Mine taught the MPC; my roommate's taught the common law. It was a hellacious shock to start practicing and realize that the MPC has absolutely nothing to do with the practice of criminal law in Virginia. I learned more that was pertinent to my actual practice from having helped my roommate study the common law definitions and listening to him repeat the definitions over and over again to memorize them. And, yes, Virginia does use common law definitions for many crimes (not statutory). Groot's Criminal Offenses and Defenses in Virginia has been as important to the practice as the statute books (not sure what's going to happen now that he's gone).
I realize there are States out there which have adopted a penal code. However, a code would have it's basis in the common law and therefore it would logically be easier to upgrade one's knowledge from the common law to the code. The common law is not in any manner based on the MPC (don't even try to argue it in a Virginia court) and therefore the MPC may have to be unlearned in order to practice effectively.
Please don't send more students out to places like Virginia improperly trained.
