People v. Harris 

Offense of aggravated kidnaping while armed with a firearm has same elements as armed violence predicated on kidnaping. Truth-in-sentencing requirement that a defendant serve 85% of his sentence for aggravated kidnaping while armed with a firearm, such that a person convicted of that offense may be eligible for lesser amount of good-time credit than someone convicted of armed violence predicated on kidnaping, does not violate equal protection clause. Although limiting the eligibility of certain inmates to good-time credit may constitute disparate treatment among those inmates, a statute does not necessarily violate equal protection where it differentiates among prisoners who committed disparate crimes. (FITZGERALD SMITH and HOWSE, concurring.)
