In this appeal from a judgment of conviction entered after a jury trial in the U.S. Dist. Court for the Southern Dist. of NY, defendant Rafiq Sabir contends that: (1) 18 U.S.C. 2339B, under which he was convicted for providing and conspiring to provide material support to a terrorist org., is unconstitutionally vague; (2) the trial evidence was insufficient to support his conviction; (3) the gov't's. use of peremptory juror challenges exhibited racial bias in viol'n. of the 14th Amend.; (4) erroneous evidentiary rulings violated his rights to a fair trial; (5) the dist. court abused its discretion in addressing alleged juror misconduct; and (6) the gov't's. rebuttal summation deprived him of a fair trial. This decision rejects these arguments as without merit. This is a print on demand pub.
