Confused on answer choice D

D) states: "A well-paid police force is sufficient to guarantee a good legal system some bad governments have good legal systems" Aside from the fact that there is some punctuation missing from that sentence, I don't see how we arrived at the conclusion that "some bad governments have good legal systems". The first part of the answer is fine, but in diagramming the stimulus info, I get the following: LS (legal system) & PF (police force) -> FAG (foundation of all governments) Contrapositive: Not FAG -> (not)LS OR (not)PF Second premise: (not)PPW -> (not)GLS Contrapositive: GLS -> PPW Stimulus conclusion: PPW -> GLS I see how this is mistaken reversal of the second premise, so I understand answer choice D saying "a well-paid police force is sufficient to guarantee a good legal system", but where did the part about some BAD governments having legal systems come from?? Thanks!
