• Retained by plaintiff’s counsel and by the defense alike, in civil and criminal matters.
• Fees are published: a $9,000 flat fee covering discovery review and the written expert report; the full schedule is on For Retaining Counsel.

Retained in plaintiff false-arrest cases and in the defense of officers accused of false arrest.

An arrest is made in the field on what the officers knew, and the officer who makes it is not always the officer who learned the facts behind it. The basis can arrive as a dispatch broadcast, another officer's request to stop and hold someone, a records or warrant return, or a warrant held by another agency. Reading that kind of arrest, a false arrest expert witness follows the knowledge itself: who first learned each fact, in what words it was passed on, by what channel, and what reached the arresting officer before the person was taken into custody.

Each channel leaves a different record, and the questions change with the channel. For a broadcast, they are what the broadcast said and what the arresting officer matched to it. For a request from another officer, they are what the requesting officer knew, how much of it was passed on, and whether the arresting officer asked for more. For a records or warrant return, they are whether the record was current, whether it belonged to the person being held, and whether the agency holding it was asked to confirm it.

The analysis sets what was sent beside what was received and acted on, because detail can fall away or be added between the officer who held a fact and the officer who used it. The dispatch side of that trace is read as the Library guide to CAD reports describes. Confirmation is measured against the agency's policy and the officer's training in force on the date, and against generally accepted police practices: which confirming steps were required before custody, which were available at the scene, and which the record shows were taken.

A required confirmation that appears nowhere in the record is reported as unrecorded; one the record shows was skipped is a departure. Both are findings about police practice, stated as such; neither says the arrest was unlawful or that anyone is liable for it. The trace ends in an attribution for every fact in the arrest's basis: the officer who first held it, the channel it traveled, and whether the record shows it reaching the officer who acted on it.

The same arrest can be examined in a civil case and in a criminal one, and the analysis arrives in a different form in each. In a civil claim under 42 U.S.C. § 1983, the work of a false arrest expert witness can take the form of a written report stating the trace and the document comparison as opinions with their basis, a deposition in which opposing counsel tests them, and, where the other side has disclosed an expert who reads the arrest differently, a rebuttal report. The vocabulary of each, from disclosure to rebuttal, is defined in the lexicon of expert litigation terms.

In a criminal case the defense may need the analysis at a suppression hearing, well before any trial, where it is delivered as testimony; that engagement runs through suppression support. The format, the calendar and the audience change between the two proceedings. The method does not: the same trace of who knew what and how it reached the arresting officer, the same reading of each document against the others and against the dispatch record and the video, and the same measures, taken from the policy and training in force on the date of the arrest.

Nor does the method move with the retaining side: counsel defending officers accused of false arrest retain it unchanged, and the Library sets out why that consistency matters at trial for an expert retained by both sides. The report and the testimony address police practices, and legal conclusions remain counsel's. An arrest that grew out of a stop is traced back to the first contact under stops, frisks and detention, and probable-cause timing takes up a dispute over when the basis arrived, rather than how it traveled.

Custody does not close the record. For each search that followed the arrest, whether of the person, a vehicle or a home, a false arrest expert witness reads the paper the agency made about it: the basis entered for the search, and whatever inventory form, property receipt, evidence log entry or record of consent it produced. Where cameras were recording, the video fixes the order in which those searches happened. Search terms such as a search incident to arrest are defined by the lexicon of stops, arrests and searches, and a home searched on a warrant is read as set out in warrants and no-knock entries.

The first comparison sets the basis each record states for a search beside the sequence the timestamps and the video show. An inventory is fixed in that sequence by whatever times the inventory form, the dispatch record and the video give for it, and a consent by when the request was made, when it was answered and when the search began. Where two records give one search different bases, both are reported, each with its source.

The second comparison runs against the agency's own procedure, as it stood when the search was made. Where the inventory or consent policy names steps, forms or a responsible officer, the analysis looks for each of them in the inventory form, the property receipt, the evidence log and any consent record.

A gap is stated as the record shows it: a consent form timed after the video shows the search under way, an inventory the report describes with no inventory form in the record, a step the policy required that no record reflects. A false arrest expert witness reports where the paper and the sequence diverge and goes no further: the report infers nothing about why, and it characterizes no officer's reason for a search. A departure from the agency's procedure is a finding about practice, not a constitutional finding, and it does not establish liability; legal conclusions remain counsel's, and the expert addresses police practices.

The threshold for the arrest itself is a separate question, taken up in reasonable suspicion versus probable cause. So is a dispute over where an item first appears in the record, which is taken up under fabricated or suppressed evidence.

Case accounts as published by retaining counsel. Outcomes depend on their facts; no result is promised for any other matter.
