Officer and civilian counts are full-time employees as filed by the agency in its annual return. A dash means the agency did not report that figure for that year — it does not mean zero.

Crime and clearances

Offences and clearances filed by Mokena Police Department in its monthly returns to the FBI, added up by calendar year, 2019–2026. Violent crime and property crime are the FBI’s two categories. These are the counts as filed: Police Census does not turn them into a rate.

Reading the table. “Not reported” means the agency filed nothing for that year; it does not mean zero. A 0 is a figure the agency filed. For 2026 the FBI is still collecting: that year is not complete in the file we read, so where this agency has no 2026 figures the table says “Not yet in the FBI’s file” rather than “Not reported”. We can see that the agency is absent from the file so far; we cannot tell whether it has not filed or has not yet been published, and we do not guess. A year marked “7 of 12” adds up only the months the agency filed, so it is not a full-year total. A dash in the last column means the percentage cannot be worked out: it needs both figures, and at least one offence.

“Cleared” is the FBI file’s clearance count for the year. Clearances in a year can relate to offences from earlier years, so the percentage is not the share of that year’s offences that were solved, and it can exceed 100%. Figures are not adjusted: a year far below the agency’s neighbouring years, or a 0 beside many offences, may reflect what was submitted rather than what happened. The file does not say which, and Police Census does not guess.

“Not reported” means the agency filed nothing for that year; it does not mean zero. A year marked “7 of 12” adds up only the months filed. For 2026 the FBI is still collecting, so an absent agency reads “Not yet in the FBI’s file”: absent from the file so far, which is not the same claim as having filed nothing. A 0 is the figure as filed: the file does not distinguish an agency that made no arrests from one that did not submit them, and Police Census cannot either.

Bias-motivated incidents in the FBI’s file

2 incidents appear in the FBI’s hate crime file for Mokena Police Department for 2022, as at 14 August 2026. The table lists every year from 1991 to 2025 for which the file has at least one.

1 of these incidents records more than one bias motivation. The FBI’s file stores those as a single list; each is shown here as its separate entries joined by “+”, and none is added to a line in the table above.

Absence from this file is not a zero. The file lists incidents that were reported to the FBI. An agency can be missing from it because it recorded none, because it did not report, or because it does not take part in the FBI’s hate crime program, and nothing Police Census holds can tell these apart. In any one year the file lists incidents for only a minority of the agencies the FBI counts as reporting.

The figures are counts of incidents as they appear in the file, as at 14 August 2026; Police Census does not turn them into a rate and does not compare them with other agencies. Offence and bias wording is the FBI’s own, unaltered. Source: FBI Crime Data Explorer, additional datasets, hate crime bulk file, agency record IL0992200.

Assaults on officers

Officers of Mokena Police Department assaulted in the line of duty, by the weapon reported, between 2023 and 2024. These are the FBI’s own weapon categories.

20240060

Why there is no single total here. The FBI publishes two breakdowns of the same assaults — by weapon, and by how the officer was deployed — and nationally they do not agree: the assignment columns sum to 1,869,337 and the weapon columns to 1,744,852, and the two match on only 84% of rows. Police Census publishes the weapon breakdown as the FBI states it rather than picking one basis and calling it ‘the total’. The file’s ‘cleared’ column is not shown either: it sums higher than the assaults themselves, so it is not a subset of what is above and we have not established what it counts.

This comes from the FBI’s Law Enforcement Officers Killed and Assaulted programme. Despite the name, the file carries no officers-killed data at all — those columns are empty for every agency and every year, so this page reports assaults only and says nothing about officers killed.

LEOKA identifies agencies by name, not by the ORI used elsewhere on this site. A row was attached only where exactly one agency in that state reduces to the same base name; 78.7% of rows matched nationwide. An agency with nothing here may have reported no assaults, or may be one of the names that did not match — Police Census does not guess which.

Jurisdictions overlap. These agencies are also recorded against the same county, so a single address may be covered by more than one of them.

Agency identity, type, jurisdiction, coordinates and reporting status are as published by the FBI Crime Data Explorer, agency record IL0992200. Police Census reproduces these values without adjustment. Where the FBI publishes nothing, this page says so rather than estimating.
