The day after protests turned violent at UCLA, faculty members held a conference addressing the protests and the university’s response.

"Last night I went to bed at around 4:00 a.m. with student’s blood on my hands and I'm not speaking figuratively," UCLA Assistant Professor Nicholas Shapiro said. "I mean, a student collapsed into my hands with blunt force trauma and mace in their eyes, and I had to treat them."

The protests led to 15 injuries, including one hospitalization, according to officials.

"This is a failure of our institution and we need to put a stop to it today," Shapiro said.

UCLA Associate Professor Bharat Venkat also addressed the violent scene on campus, saying, "It felt like walking through a war zone."

"They're screaming, they're crying," Venkat said of the student demonstrators. "They're having a difficult time breathing. This shouldn't be happening anywhere and this shouldn't be happening here at UCLA."

University of California President Michael V. Drake addressed the ongoing protests at UCLA that "turned violent" overnight, announcing in a statement on Wednesday an "independent external review" has been ordered.

The university summoned mutual aid from LAPD officers to "restore control" to the protest, according to Drake, who noted, there were 15 injuries, including one hospitalization, that stemmed from the protest.

"My office has requested a detailed accounting from the campus about what transpired in the early morning hours today," Drake said.

"But some confusion remains, therefore we are also ordering an independent external review of both UCLA’s planning and actions, and the effectiveness of the mutual aid response," Drake said.

UCLA's own chancellor, Gene D. Block, also promised an investigation.

"We are still gathering information about the attack on the encampment last night, and I can assure you that we will conduct a thorough investigation that may lead to arrests, expulsions and dismissals," Block told the campus community in a note Wednesday afternoon.

Block, in his note, said it was "a group of instigators" who came to Royce Quad to "forcefully attack the encampment that has been established there to advocate for Palestinian rights."

He called the overnight violence "utterly unacceptable."

"However one feels about the encampment, this attack on our students, faculty and community members was utterly unacceptable. It has shaken our campus to its core and — adding to other abhorrent incidents that we have witnessed and that have circulated on social media over the past several days — further damaged our community’s sense of security," his letter read.

Of the approximately 280 arrests at Columbia University and City College, 170 are summonses, while the remaining people will receive desk appearance tickets or will work through the court system, according to Manhattan District Attorney Alvin Bragg.

Each case would be evaluated individually, including a review of body camera footage and other evidence, Bragg said. But, he did not reveal how many of those arrested were affiliated with the colleges and how many were outside agitators.

Columbia University announced final exams will be held remotely amid a tense campus climate, according to a letter sent out by the university's provost.

"In order to address the concerns of our members in an evolving campus environment, all academic activities for schools on the Morningside Heights campus will be fully remote for the remainder of the semester (with carve-outs noted below). Any remaining class meetings, review sessions, or office hours should be held fully remotely, and all final exams and other final assessments should be fully remote," Columbia said in a statement.

All final exams scheduled for Friday will be automatically rescheduled for May 10.

The LAPD and California Highway Patrol are facing backlash over not intervening in the UCLA protests sooner, as violence broke out overnight, however, law enforcement sources told ABC News the hesitancy came from jurisdiction over the campus.

The LAPD and CHP don’t have jurisdiction over UCLA and cannot unilaterally race in because UCLA has its own full-fledged police department and dispatch center, sources said.

The delay, as described by sources, was due to UCLA and its police department not authorizing a response.

UCLA’s limited police force was overwhelmed and tried to deal with the protest internally, according to sources, until the call to the LAPD and CHP was eventually made.

The protests led to 15 injuries, including one hospitalization, according to officials.
