and then claim that he has the Fifth Amendment as a shield to prevent production of the moving picture films at a hearing which the courts must conduct on the obscenity issue. " ” ” The Fifth Amendment cannot be used in an obscenity case where the material in issue has been openly displayed to the public to foreclose the production of the material in issue at an adversary hearing.” (- Colo__,_, 521 P. 2d 166, 170.)
We decide that this precedent is valid, and that the detective, in viewing the film “Deep Throat” exhibited at defendant’s theater on November 2 (after the court had already ruled as to its probable obscenity), had reasonable grounds to believe that defendant was engaged in the commission of the crime of obscenity and was authorized to arrest defendant without a warrant and to seize the material in public view as evidence.
During his case in chief, defendant made an offer of proof that on January 10 and 12,1974, the theater exhibited the film “Deep Throat” without an admission charge, and that each person coming to see the film was given a mimeographed card “that we had made up.” There was a box in the lobby where the completed questionnaires could be deposited. The offer included testimony of defendant that “some of the people” dropped cards in the box each day as they left, and that “the majority did”; that he took the cards from the box to his office; that 180 were received and that they are in the same condition as he received them without any alteration or change of number. The offer included that the questions on the card were as follows:
“(a) Did you find ‘Deep Throat’ offensive? yes or no
(b) Would you rate the overall quality of ‘Deep Throat’ excellent, good, fair or poor?
(c) Did you find the film to be entertaining and enjoyable? yes or no
(d) Would you like to view other films of this type? yes or no
(e) Did you feel consenting adults 18 years and older have a right to view films of this type? yes or no
(f) Is there any other adult film you like better than ‘Deep Throat’? yes or no If yes, give title.
(g) Why did you like ‘Deep Throat?’
A space was then provided on the cards for name, address, sex, age, occupation and marital status of the viewer. The court sustained the State’s objection to the foregoing testimony and denied defendant’s offer of proof. Defendant claims that these rulings constitute error.
The statute, at section 11 — 20(c)(4) of the Criminal Code of 1961 (Ill. Rev. Stat. 1973, ch. 38, §11 — 20(c)(4), provides that in any prosecution for an offense of obscenity evidence shall be admissible to show the degree, if any, of public acceptance of the material in this State. At 6
