The Institutional Negligence Defense: Why Ignorance Is No Longer Available

A Supplement to Constructed Guilt

Preamble: On Knowledge and Choice

This supplement addresses a single, narrow question: At what point does continuing a policy despite evidence of a superior alternative constitute institutional negligence?
