Regarding federal crimes, the founding fathers supported federal crime laws. How does this fit with your contention that the founders disapproved of designating offenses as federal crimes?
Why?
And as far as the founding fathers supporting federal crime laws, can you please give me an example of what you're talking about? I mean obviously, they thought that Treason, Piracy and counterfeitting was under federal jurisdiction and included that into the constitution. What other crimes did they believe were under federal jurisdiction and why didn't they include them in the constitution (or a general definition of crime)?
