Frankly OP, if I had to come into class again to take
another test just because some d-bag in the back row cheated, I would be right pissed off. In my experience, the college classroom is not a social entity; most classmates don't even know each other. The extra incentive from "angering the rest of the class" would be minimal. Just punish the student who cheated.

I guess an explanation is required on why I would punish the entire class for the transgressions of one student. As someone pointed out, some classes are in giant lecture halls. I have taken a class in one of these before and it was a class of about three-hundred people; in one of these classes I am sure you could realize the ease at which a paper with answers written on it could be passed along the back rows. Keeping this in mind, while I may have only caught one student cheating I am unsure as to how many cheated. Cheating can be a collabarative effort, and if I catch one person cheating there is no way to determine who else cheated, and the caught student's word is not reliable.
This is basically an argument from ignorance suggesting that because we
can't know if someone else was cheating, we
do know someone was, and since we can't know who we must punish all to be sure and get them. But consider this -- even if everyone in the back 3 rows of the hall was cheating, that's only around a 3rd or maybe a 5th of the class. How many more innocent students are hurt by this than guilty ones?
