Don't really do shades of grey of do you?
Because apparently I need to spell it out for you, I'm not saying anyone is advocating the death penalty for fraud. My point, which shouldn't need spelling out, but apparently does, is that miscarriages of justice occur. Depressingly easily.
If you could say with 100% certainty every conviction was correct, then it's maybe a different debate. But we're nowhere near.
And the OP is against the death penalty by the way. His point is this case is so shocking and emotive, it makes him want to make an exception. Which I very much get.
