Sadly, I've watched so few rounds that I've yet to see something truly noteworthy.
"PBET is good because it helps preserve the right to a speedy trial." (Obvious comeback: sure, for one person. But only at the expense of another.)
"Justice is the administration of law. More administration of law = more justice."
"If a prosecutor isn't out to commit harm, then why are they prosecuting?"
How not to win a CX exchange:
"My value is justice, which is deeper than the law, and presupposes the law. My criterion is attaining a legitimate result."Please: never describe self-contradiction as "debater hypocrisy."
"What does 'legitimate' mean?"
"In accordance with law."
