1) Pat Robertson proposes to have special "Christian Courts" in which
theologians will determine if a criminal acted under the direct command
of God, in which case his crime would be excused.
2) With a certain elegant symmetry, there would also be a special force
of "Christian Police", whose job would be to round up persons that were
going to be committing crimes in the future, again as per divine
revelation.
3) Robertson has also claimed that God on occasion orders the
destruction of an entire people for their sinfullness. This is in order
to keep Hell from being overpopulated by their descendents! He doesn't
give an explicit plan for translating this into policy.
Maybe it's part of a plot to make George Bush seem reasonable.
