Warren E. Burger,
Furman v. Georgia — Dissenting Opinion
“ Comparative deterrence is not a matter that lends itself to precise measurement; to shift the burden to the States is to provide an illusory solution to an enormously complex problem. If it were proper to put the States to the test of demonstrating the deterrent value of capital punishment, we could just as well ask them to prove the need for life imprisonment or any other punishment. Yet I know of no convincing evidence that life imprisonment is a more effective deterrent than 20 years' imprisonment, or even that a $10 parking ticket is a more effective deterrent than a $5 parking ticket. ”
