> he received Saturday detention and a grade of 65 out of 100 on the assignment

The student still received a passing grade for the assignment despite some of the assignment being AI hallucinated text. From my experience, plagiarism is an automatic zero for the entire assignment or course, but there are tons of counterexamples when the teacher/professor doesn't want to deal with the academic integrity process.

- "but there are tons of counterexamples when the teacher/professor doesn't want to deal with the academic integrity process"

That's a good point: in this particular case, the teacher of the course was subpoenaed to federal court and compelled to testify about their grading. Incredible burden, for someone else's problem.

I have had the rare privilege to see up close examples of how at several US universities, when professors are presented with irrefutable proof that a student has cheated (well beyond any reasonable doubt) the professor will most often do nothing. In the best case they will meet with the student and give them a stern talking to.

The whole system is set up to disincentivize any effort to actually hold students accountable for cheating in a significant way (fail assignment, fail course, expulsion, etc.)

When we read about cases of students being held accountable it's generally the exception not the rule.

Fail to meaningfully discipline students due to fear of litigious moron parents, get sued by litigious moron parents anyway.

There need to be counter claims to cover these costs instead of it falling on taxpayers.

Last I checked, 65 was a D-, not a C+. So the C+ was for the course.

Grading scales vary. 65% could correspond to any letter grade.

also disciplinary action and very probable expulsion

At a university that takes their rules seriously, perhaps. Absolutely not expulsion at any k-12 school.
