GREENBELT, Md. (DC News Now) -- Top officials from the University of Maryland (UMD) answered to a lawsuit filed in federal court, testifying in a case brought by a Palestinian student group earlier this month. A federal judge is now weighing those arguments heard in court in Greenbelt on Monday. Groups supporting Israel and groups supporting Palestine had reserved space on campus to demonstrate next week on Oct. 7, marking one year since Hamas attacked Israel, igniting a war between the two. Thousands of people have died in the war since the attack. Palestinian student group sues UMD for not allowing vigil on October 7 The university later reversed its decision to allow those events, citing threats and safety concerns. The university said the groups could still hold the events, just on a different day. UMD Students for Justice in Palestine (SJP) filed a lawsuit against the university, alleging the rescheduling or canceling of their event violated the students' First Amendment rights. The group argued they should be allowed to hold what they're describing as an interfaith vigil on October 7th. SJP's legal team and its members said it is the university’s responsibility to make it a safe space for students to exercise those rights. "One person was threatening to do a [Ku Klux] Klan march on campus to threaten SJP," said Daniela Colombi, a UMD SJP board member who testified in court Monday. "Our issue is that it's the school's responsibility to protect us from these people and by dealing with these situations seriously." University of Maryland Police Chief David Mitchell, who has held his position at the school for 14 years, also testified in court Monday. He shared concerns about high tensions on campus over the last year, and what he expects to see on that particular day.

He testified about the violence he's seen on other campuses, including nearby George Washington University, which saw police, students and outsiders clash this past spring. Mitchell said thousands of emails have come in to the school, some including threatening language about the group's Oct. 7 plans. "It's horrifying. 'Locked and loaded, I'm coming for you.' Very specific, violent language. This is not an issue against our students, this is about protecting our students," Mitchell said after he testified Monday. The judge's questions centered around the school's ability to hire additional outside security or coordinate with other police departments to help in case something happens on Oct. 7. The judge said to expect a decision issued by noon Tuesday.
