[3, 4] Entrapment does not occur when government agents merely afford the opportunity to do that which a person already has a predisposition to do. See Jackson v. State, 12 Ark. App. 378, 677 S.W.2d 866 (1984). Entrapment as a matter of law is established only if there is no factual issue to be decided. Ordinarily, it is a question of fact. Walls v. State, 280 Ark. 291, 658 S.W.2d 362 (1983).
See Harper v. State, 7 Ark. App. 28, 643 S.W.2d 585 (1982). Furthermore, such evidence is usually admissible in rebuttal to the defense of entrapment. Jackson v. State, 12 Ark. App. 378, 677 S.W.2d 866 (1984). In response to appellant's objection, the prosecutor stated that the purpose of this testimony was to rebut appellant's asserted defense of entrapment.
