Have you Defined Pedophilia?...
Alabama's Age Standards are Notably Different than Cali's...
Putting someone to Death is Serious Business, and I don't Think you would want a Standard where you could Marry in one State and be Executed for the same in another.

We do not have a Federal criminal law defining pedophilia applicable to all the states. Instead, on the issue of criminalizing certain behavior, it is now as it has always been: a matter reserved to the states.
Many conservatives decried the SCOTUS decision that voided Texas' law prohibiting homosexual sodomy (supposedly on due process grounds). The complaint was not that we particularly give a damn about such behavior. The complaint was that the Supreme Court had no legitimate Constitutional basis to insert itself into a State matter.
It seems to me that any state that has a law prohibiting sexual relations with children on its books SHOULD carefully define the gravity of such offenses on a clear basis. Age works. And the various sentencing options for each level of felony should also be clearly defined. And if that leads to different outcomes in different states, that's not a valid concern of the SCOTUS.
