State's expansion of residence restrictions for registered offenders was not an ex post facto penalty, as the conduct regulated is post-enactment knowing residence. The law does not amount to a taking, since it is a regulation on the use of property, doesn't affect the market value of the property, and plaintiffs acquired the property after enactment. Procedural due process does not require individual hearings. The law has a rational basis.
