Bring back ...

.
... the guillotine:

There are other, less dramatic, ways, of course. Hanging and firing squads would probably be quicker and more painless than lethal injection or the electric chair. But the guillotine really seems to solve everyone’s problems: It was designed to deliver an efficient, quick, and painless death. It performs that task admirably. I understand the irony of a reactionary such as myself embracing the Terror’s preferred method of execution, but one must give credit where it’s due.

 The author rightly points out that most of the modern methods of execution are for the publics' benefit, not any constitutional reasons; the public just wants it to go quietly and with no visible blood.

As I mentioned in a previous post, I'm not opposed to the condemned suffering a little (or even an amount commensurate with his victim); I just wouldn't want to bring back medievel torture.
