I'm still reading How Doctors Think and it continues to increase my awareness of all the ways and reasons that a doctor can arrive at an incorrect diagnosis. I suppose a jury could come to an incorrect verdict in many of the same ways...

This link tells of six medics who face the death penalty because they gave HIV tainted blood to children. The story is painfully incomplete. Did the medics know that this blood was tainted? Is this terrible effort to punish them simply an attempt by the bereaved to gain justice in the "eye for an eye" sense?

It is hard for me to imagine any doctor intentionally infecting children with the HIV virus. And so much less likely that six of them would do it....knowingly.
