Two weeks ago. on "Prime Time Live." a television show airing on ABC. Americans saw for themselves what has become an all too common practice of prisoners routinely executed and their organs sold to people willing to pay $30.000 for a kidney. What is even more troubling is that Chinese nationals living in the United States on student visas are marketing these organs to Americans and other foreigners who are able to make a $5.000 deposit and then travel to China and be admitted to a Chinese Army hospital where they will receive their kidney after they have been tissue and blood typed. According to Amnesty Internationals August 1997 report. China has executed at least 3.500 prisoners this past year and many reports say this number is closer to 4.000.
