People are ruthless. Not any particular nationality or race - we all are. However, the scary thing is that in China, the value of human life is relative a times. In the past, prisoners are executed by a corrupt and elitist justice system to harvest organs.
And with crackdowns and less executions, it's possible a boy, found drugged with his corneas missing is a victim of those involved in organ trafficking.
Police have denied it. Of course they would. This is China after all. Police have arrested a woman who was involved. Guess who just volunteered to donate her organs?
