Court of Appeals for the Fifth Circuit June 1, 1972, 71-3477 (United States v. Richard Alston)

GOLDBERG, Circuit Judge:

Although there are four targeted errors in this appeal, the most vexatious involves the right of a trial court to stifle factual disclosures without demonstrable significance to a defendant but danger-laden to the witness. Appellant, Richard Alston, was convicted by a jury of selling heroin in violation of 26 U.S. C.A. §§ 4704(a) and 4705(a).
