"That relatively few criminal cases in this country are resolved by full Perry Mason-style strials is fairly common knowledge. Most cases are settled by a guilty plea after some form of negotiation over the charge or sentence. But why? The standard explanation is case pressure: the enormous volume of criminal cases, to be processed with limited staff, time and resources. . . .
