Turner Broadcasting System, 512 U.S. at 662; Minnis, 2016 IL 119563, ¶ 44. ¶ 91 Because the invalidation of a statute on overbreadth grounds is “strong medicine,” it is to be applied “only as a last resort” and where the statute is not subject to a limiting construction. Broadrick, 413 U.S. at 613; see also Relerford, 2017 IL 121094, ¶ 51. If a statute is “ ‘readily susceptible’ ” to a narrowing construction that will eliminate its substantial overbreadth, the statute must be upheld. Virginia v. American Booksellers Ass’n, 484 U.S. 383, 397 (1988) (citing Erznoznik v. City of Jacksonville, 422 U.S. 205, 216 (1975)); see also Hicks, 539 U.S. at 118-19. ¶ 92 To resolve defendant’s overbreadth argument, we must determine whether section 11-23.5(b) impermissibly restricts constitutionally protected expression in a substantial number of its applications when considered in relation to its “plainly legitimate sweep.” See Stevens, 559 U.S. at 473; Williams, 553 U.S. at 292-93. As explained above, the statute includes several elements that operate to significantly limit its application. ¶ 93 In light of these detailed restrictions that serve to confine the sphere of proscribed conduct, we conclude that section 11-23.5(b) is not overbroad. The statute prohibits a certain and limited category of knowing conduct that involves the unauthorized and intentional dissemination of an intensely personal image of another person. It encompasses only an image of a private and sexual nature, which the disseminator must know or understand is to remain private and which is disclosed without the consent of the person depicted in the image. Given the narrowly focused scope of section 11-23.5(b), we conclude that the statute does not prohibit a substantial amount of protected speech when judged in relation to the statute’s legitimate sweep. See Stevens, 559 U.S. at 473; Williams, 553 U.S. at 29293. As such, it does not burden substantially more speech than necessary to advance its substantial governmental interest. Turner Broadcasting System, 512 U.S. at 662; Minnis, 2016 IL 119563, ¶ 44. ¶ 94 Despite the fact that the statute includes the several narrowing factors previously discussed, defendant argues that the circuit court correctly determined that section 11-23.5(b) is unconstitutionally overbroad. As support of its overbreadth determination, the circuit court posited several hypothetical scenarios - 29 -
