In Britain, there used to be a concept of "capital theft" were execution was the default punishment for theft beyond a certain amount. That would be similar to your idea.I believe the death penalty should be available, for certain crimes.
I would add a new category of crimes subject to capital punishment - economic terrorists. Remember Enron, where top management ran the company into the ground? And where employees were encouraged to invest in Enron stock for their retirement accounts, only to lose every penny? How many families suffered due to top management's actions? How many people's retirement was reduced or lost? Some of those fucks in Enron top management should have ridden the lightning. Bet you'd see a lot less of such shit if economic terrorists were executed.
Also believe the present appeals process goes on way too long. All appeals should be complete within two years, max.
If the death penalty were applied on a more timely basis the deterrent value would be enhanced. As it is, the death penalty merely ensures the person executed will commit no more crimes.
Not only should executions be televised and streamed, they should be done on a pay-per-view basis, with at least 50% of the profits going to the victim(s) of the person being executed.
