Staffing
Staffing data not available. The FBI's national staffing census (LEE) does not separately track county corrections facilities, sheriff's offices, or other county agencies in New Jersey -- only a single statewide Department of Corrections figure exists in that data. See the methodology for what FBI staffing data does and does not cover.
Military surplus equipment (1033 program)
No 1033 transfers recorded. No surplus-equipment transfers appear for this agency under a high-confidence name match in the Defense Logistics Agency's file as of 2026-06-30. That can mean the agency received nothing through the program, or that a recipient name in the federal file did not confidently match this department. See the methodology for how the match is made, or the statewide 1033 overview for how the program spreads across New Jersey.

Against peers, 2025
How this grade was built →| Warren County Sheriff's Department | 100.0 |
|---|---|
| County median, county sheriff (1) | 100.0 |
| NJ median, county sheriff (20) | 115.2 |
Investigations per 100 officers named in that year's IA investigations (the Attorney General's own "Number of Officers" field, a distinct-officer count drawn from the IA case data itself, not a department headcount). A higher number is ambiguous on its own: it can reflect more misconduct, or a stronger internal reporting culture. Medians are computed within the same agency type only.

What this grade can and can't tell you
- The underlying data is self-reported by agencies, one yearly snapshot at a time.
- Allegations are not findings; many complaints end unfounded, exonerated, or not sustained.
- There is no arrest or call-volume denominator in this data, so nothing here is a per-capita misconduct rate. A genuinely independent staffing-based rate, sourced from the FBI rather than this grade's own data, appears above when available. It is a different measurement, not a more accurate version of the grade.
- A higher internal affairs volume is ambiguous: it can indicate more misconduct, or a more robust oversight and reporting culture. The grade weighs it anyway, because volume is what the record offers; that choice is published, not hidden.
- The grade is one lens. The records it reads are on this page above.

Major discipline records
No major discipline records appear for this agency in the 2020-2025 releases. Absence of records is not a finding; see the methodology for what this data does and does not cover.
Public records requests
No records-request history is shown for this department. OPRAmachine, an independent site that files and publishes Open Public Records Act requests, has no public body that confidently matches this department, so this site does not assert one. That does not mean nobody has requested records from it. (Checked against a snapshot of OPRAmachine taken 12 July 2026.) See the methodology for how the match is made.
