HANOVER — The Hanover Police prosecutor filed charges on Thursday in Lebanon District Court for the last batch of the 89 people arrested on May 1 during a pro-Palestinian protest on the Dartmouth Green.

Prosecutor Mariana Pastore charged 20 additional protesters with violations and opted not to charge four, including Dartmouth History Professor Annelise Orleck, with criminal trespass.

“I am of course personally relieved to no longer be facing criminal charges,” Orleck said in a Friday email. “But that does not erase the trauma of what happened to students, faculty and community members on May 1.”

New Hampshire State Police troopers held Orleck, who is in her mid-60s, on the ground as they arrested her along with scores of others within two hours of a handful of tents being erected on the Dartmouth Green on May 1. Dartmouth officials called police to remove the protesters, who had gathered in response to the ongoing war between Israel and Hamas in Gaza, and did not comply with repeated warnings to disperse.

“I have never received an apology from Dartmouth or from the state police for their violent assault on me or for the brutality they unleashed against an entirely peaceful protest,” Orleck said in her Friday email. “I believe that I am owed one, as are we all.”

Pastore, reached by phone on Friday, declined to comment on active cases, so it remains unclear how she determined which protesters to charge and which to let off.

Combined with charges Pastore previously filed in June, of the 89 protesters arrested in Hanover in May, 55 have been charged with violations and 32 haven’t been charged. Violations do not carry jail time, nor can they result in a criminal record, but fines and court fees may be imposed.

While Orleck said she’s relieved that the students arrested May 1 will not have criminal records, she described the charges as “totally unjust.”

“They should not be facing any legal repercussions,” Orleck said. “They did nothing wrong. The aggressors on May 1 were the police.”

In May, soon after the arrests, charges were dropped entirely for two reporters for The Dartmouth student newspaper.

Meanwhile, Andrew Tefft, a 1997 Hanover High School graduate who lives in Watertown, Mass., is the only person arrested that night who faces a misdemeanor charge for resisting arrest. If convicted, he faces up to a year in jail.

Criminal charges also remain pending against Kevin Engel and Roan Wade, who were arrested for criminal trespass last October when they erected a tent in front of Dartmouth President Sian Leah Beilock’s office in Hanover.

“All they did was sit in a tent,” Orleck said of Engel and Wade. “The right to peaceful protest is the bedrock of democracy. It is time for this whole trauma to end.”

Orleck maintains that the only “just outcome” would be for the college to “publicly request that the prosecutor drop all charges, issue an apology to those of us who were brutalized that night and promise never again to bring riot police onto campus.”

Earlier this week, the ACLU of New Hampshire called on both Dartmouth and the University of New Hampshire to drop trespassing and disorderly conduct charges against pro-Palestine protesters arrested on May 1.

The 20 protesters who were charged with violations this week are scheduled to be arraigned on Aug. 5, although they can file waivers of arraignment as many in the previous group did ahead of their arraignment date earlier this week.
