Legal Question in Technology Law in Michigan

I am not aware of any state that prohibits a minor from looking at pornography. Most states prohibit people and businesses from providing material "obscene for minors" (sometimes called "harmful to minors" though no harm is required) to a minor, but the focus of the laws has always been on providing the material to the minor -- not on punishing the minor. Indeed, I think there would be a very serious First Amendment issue if a state attempted to punish a minor for looking at pornography.
