Dear President Alivisatos and Provost Baicker,

Allowing the continued encampment of protesters on our main quad imposes the following significant costs on the University:

1. Time, Place, and Manner (TPM) restrictions are put in place to ensure that expression furthers the goal of intellectual exchange in the pursuit of truth. Flagrant violations of TPM restrictions undermine the purpose of the University.
2. TPM restrictions are not being applied equally. If the University continues to allow TPM violations by these protestors, while enforcing TPM restrictions on other groups, it is effectively violating the principle of institutional neutrality outlined in the Kalven report.
3. It prevents us from hearing opposing viewpoints since these protestors have repeatedly ripped down and removed posters, flags, and banners they disagree with and shouted down speakers they disagree with.
4. It provides an incentive to engage in TPM violations and encourages future encampments. We risk chaos and the collapse of our ability to function as an institute of higher learning.  

This flagrant violation of our academic values is not going to end unless you take decisive action to remove and sanction these protestors while firmly rejecting their demands.

Sincerely,

Dorian S. Abbot, Professor of Geophysical Sciences
