Gregory K. Hopkins, Appellant v. the State of Texas, Appellee

Summary

The Court of Criminal Appeals of Texas affirmed Gregory K. Hopkins' conviction for unlawful possession of heroin, holding that the trial court did not err in refusing a mistrial despite prejudicial testimony and correctly excluded psychiatric testimony for impeachment purposes. Justice Morrison concurred in part and dissented in part, agreeing with the conviction but criticizing the absolute prohibition on psychiatric impeachment.
