Kent State University officials confirmed this week that security measures for the Sept. 29 open-carry walk cost the university $65,000.

The cost included personnel — overtime, additional Kent State officers and dispatchers — supplies, facility preparation, transportation, communications and meals.

More than 300 officers were on the Kent campus for the event, including Ohio State Highway Patrol, which is still determining the cost to the organization.

The city of Kent, which had extra officers on duty, estimated costs to its police department were below $5,000.

Several other organizations — including deputies from the Portage County Sheriff's Office and officers from Ohio University, University of Akron, Ohio State University, Metro SWAT and the University of Cincinnati — were on hand during the walk. The sheriff's office also was still working to determine costs.

According to a report from Kent Wired, university President Beverly Warren said Kaitlin Bennett, a Kent State alumna who organized the open-carry gun walk, cannot be billed for the costs because the event was not registered with the university. Bennett has stated publicly she believes the protesters like Antifa who were present at the walk should be responsible for the costs.
