"If you had been Catiline, what would you have said to undermine Cicero's case?"

     If I had been Catiline, I would have confronted Cicero on many of his accusations.  Cicero seems to have accused Catiline of many devious/evil things, and yet he presents no real proof to him or to the senate.  I would have asked Cicero to provide the proof that he wasn't sharing.  If there was real proof of the deeds then of course I would be condemned, but if there was no real proof I would have a tremendous advantage. I would therefore be able to represent myself to not only the senate, but also to Cicero, as an innocent individual.
