A bit heavy for a Friday I know.
So the case of Teresa Lewis has brought this debate back to the fore, personally I am opposed to capital punishment and it has nothing to do with the accused being female or not too bright.
There are plenty of practical reasons why the death sentence is a bad idea, look at the number of high profile miscarriages of justice, it's pretty hard to appeal an execution.
Morally, what does it say about the value a society places on life when the state murders its own citizens. State sanctioned murder is violence of the state against its citizenry and as a result these countries tend to be on the whole much more violent.
Personally I am glad we don't have it in the UK
