We think there is a reasonable fit here between the State’s purpose of protecting society from persons who have been determined to be likely to reoffend if not placed in a secure facility and their placement in such a facility. Therefore, Garren has failed to show a substantive due process violation. VII. Vagueness. Although Garren states in a division heading in his brief that chapter 229A is vague as applied and on its face, he makes no argument in his brief in support of the contention that the statute is vague as applied to him. We deem this issue waived. See Iowa R.App.P. 14(a)(3) (“Failure in the brief to state, to argue or to cite to authority in support of an issue may be deemed waiver of that issue.”); State v. Cooley, 608 N.W.2d 9, 13-14 (Iowa 2000) (<HOLDING>). Consequently, Garren is precluded from
