Should the criminal status of donees impact priority for organs?

The way in which organs are allocated is constantly subject to debate.  Recently, it has been reported that four Japanese gang figures received liver transplants at the U.C.L.A. Medical Center while hundreds of law-abiding patients died as they waited for organs.

According to AP, Senator Asks About Surgery on Gangsters, NY Times, June 8, 2008, Senator Charles E. Grassley (Iowa) is investigating these transplants.  At this time, however, there is no proof that U.C.L.A. or the doctor who performed the transplants knew about the donee’s ties to Japanese gangs.

The hospital and doctor have stated that they do not make moral judgments about their patients but rather just treat them according to medical need.
