So you're saying that it's legal for a man in Arkansas to kill a man in Texas because there's no law preventing it?

There is a law against it (laws don't necessarily "prevent" crime, by the way, only prescribe penalties for violating the laws)--murder is illegal in both Texas and Arkansas, according to state laws; there is no federal equivalent to state homicide law. --------------------------------------------------------------------------------

There is a law against it

There is a law against kidnapping in Texas as well. It isn't necessary that there be a federal law.

None of this really deals with the fact that Congress isn't given the power to define crimes other than the three listed in the constitution. (Excepting Washington DC of course).
