Unprecedented demands
Unprecedented action calls for unprecedented reaction. The teachers need unprecedented reaction to let the masterminds of the attack know that they will not sit still and pretend nothing has happened. Otherwise, attacks on professors might become all too common and easy like so many other evils in the country accepted as a normal part of everyday life.
Some possible unprecedented reactions: Most importantly, the teachers can demand that the post of Vice Chancellor be made non-political, that is the government should no longer appoint a Vice Chancellor. They can also demand the withdrawal of police from the university who provide no security and attack students and teachers (Dr. Anwar, Biochemistry) and replace them with a security force directly under their authority. There are many other demands open to the teachers but the two above would be unprecedented.
