re: UNC professor refusing to release grades for course.

Most of these universities have cowards as administrators. They give the whacked out element of the faculty way too much power.

What employer would tolerate employees refusing to do an essential element of their job because of concerns over protestors (particularly protestors who are violating the law)? What employer would tolerate an employee shitting all over its customers by refusing to perform their job duties?

Frankly, what kind of student would put up with some professor withholding grades?

The administration at UNC should fire every faculty member who withholds grades. There are plenty of people in this world who would love to have those faculty jobs.
