Thomas A. Barefoot v. State Texas

Appellant contends that the trial court erred by failing to instruct the jury at the guilt-innocence stage of the trial on the law of circumstantial evidence, denying his motion for change of venue, overruling his challenges for cause of three prospective jurors, refusing his request for additional peremptory challenges, admitting evidence of extraneous offenses, failing to define "probability" in the charge at the punishment stage, and overruling his objections to the testimony of two witnesses as to the probability he would commit acts of violence in the future. Appellant also contends that Art. 37.071, V.A.C.C.P., is unconstitutionally vague.
