Abe Fortas,
Giles v. Maryland — Concurrence
“ A criminal trial is not a game in which the State's function is to outwit and entrap its quarry. The State's pursuit is justice, not a victim. If it has in its exclusive possession specific, concrete evidence which is not merely cumulative or embellishing and which may exonerate the defendant or be of material importance to the defense-regardless of whether it relates to testimony which the State has caused to be given at the trial-the State is obliged to bring it to the attention of the court and the defense. ”
