Dear

This determination is issued pursuant to section 9.5(c) of the Freedom of Information Act (FOIA) ( 5 ILCS 140/ 9.5(c) ( West 2024)). For the reasons explained below, the Public Access Bureau has determined that your allegations are unfounded.

On April 16, 2025, you submitted a FOIA request to the McHenry County Sheriff' s Office ( Sheriff' s Office) seeking, in relevant part, video footage of block 3, section 1, dayroom related to a November 4, 2024, incident. On April 21, 2025, the Sheriff's Office denied your request in its entirety pursuant to section 7(1)(e) of FOIA ( 5 ILCS 140/ 7(1)(e) ( West 2024)). On May 14, 2025, this office received your complete Request for Review contesting the Sheriff' s Office' s denial.

Section 7(1)(e) of FOIA exempts from disclosure "[ r]ecords that relate to or affect the security of correctional institutions and detention facilities." In Glynn v. Dep't of Corrections, the Illinois Appellate Court held that this exemption " applies to records that could jeopardize the security of a correctional center or detention facility if disclosed, rather than any records merely pertaining to security in any manner whatsoever." 1 Therefore, when a public body withholds records under section 7(1)(e), it carries the burden of demonstrating "that disclosure of a requested record could pose a potential security risk to a correctional facility." 2 The Sheriff' s Office' s denial asserted that disclosure of the requested footage would jeopardize of the safety and security of its detention facility and correctional officers by exposing the surveillance system' s blind spots. Although the Sheriff' s Office' s justification for withholding the footage was somewhat vague and conclusory, the Sheriff's Office provided this office with a copy of the requested footage for our confidential review, and this office confirms that its disclosure could pose a potential security risk to the facility. Specifically, the footage responsive to your request for "block 3, section 1, dayroom" reveals most, but not all, of a jail common area, including significant blind spots that potentially could be exploited by inmates to evade detection of dangerous or impermissible conduct. Under these circumstances, the Sheriff' s Office did not improperly withhold the footage at issue under section 7(1)(e) of FOIA, and this office has determined that your allegations are unfounded.
