DAVID G. HOWELL

The Defense discloses David Howell in this Supplemental Discovery Response. His resume is attached as " Exhibit A. ” His prior testimony as an expert was in the Federal District of Idaho in U.S. v. Babichenko,
Case No. 1: 18-cr-00258.

At Howell & Associates, Mr. Howell specializes in Online Brand Protection, Anti-Counterfeiting, Marketplace Channel Management, and Digital Forensics, guiding brands through the complexities of platforms like Amazon, eBay, Wish, Alibaba, AliExpress, Google Shopping, and others. Mr. Howell's company protects brands and works to eliminate counterfeit threats. Mr. Howell has an extensive work history in the electronic commerce industry in the areas of brand protection, brand strategy, fraud investigations, algorithmic analysis, data manipulation risks, and market practices.

It is anticipated that Mr. Howell of Howell & Associates will testify based on his experience and education as follows:
1. Amazon data requested versus produced, form of data produced, and a forensic examination of the available produced data in this case.

Ο A forensic analysis of whether the dataset is complete, unaltered, and in a format suitable for forensic examination.

Ο Identification of gaps in data provided by the State and how missing elements impact forensic accuracy.

Ο Evaluation of metadata, timestamps, and tracking information within the Amazon data to assess reliability and forensic validity.

2. The importance of full purchase history in an Amazon account to conduct an accurate forensic examination of the data.

Ο A complete forensic review requires examining full purchase history, search logs, recommendation exposure, and product interactions.

Ο Isolated purchases or searches without full historical context can lead to misleading conclusions.

Ο Amazon's data retention and account history logs are critical in determining user behavior trends, purchase frequency, and algorithmic influences.

3. The role of Amazon's Algorithm-Driven Recommendation System and Cross-Platform Tracking.

Ο Amazon's AI and machine learning (ML) systems do not passively reflect searches; they actively shape user experience and influence product visibility.

Ο The Buy Box system prioritizes certain sellers and dynamically adjusts pricing based on Al predictions of consumer behavior.

Ο The Clickstream tracking system records user interaction data, affecting what products are suggested or displayed.

Ο Al-powered algorithms determine rankings, auto-complete searches, and personalize product placement.

Ο Amazon's data models can reinforce specific product categories, repeatedly exposing users to related items based on engagement rather than intent.

4. Omnichannel shopping extends beyond a single device.

Ο Amazon accounts are synchronized across multiple devices, including smartphones, tablets, desktops, laptops, and smart home devices (Alexa, Echo, etc.).

Ο Shared household accounts introduce forensic challenges, as multiple individuals contribute to search history, purchases, and product recommendations.

Ο Cross-device activity tracking allows Amazon to retain behavioral data across different platforms, affecting search results and purchase recommendations.

Ο Retargeting ads from Google, Facebook, and YouTube further influence Amazon's search suggestions and ad displays.

5. The Influence of Amazon's Advertising System on Click and Purchase Behavior.

Ο Amazon's advertising ecosystem is deeply integrated into the search and recommendation process.

Ο Sponsored listings, retargeting ads, and display ads shape user choices, often overriding organic search results.

Ο Unlike a simple “ search and buy ” experience, Amazon actively pushes promoted content through AI-driven ad targeting.

Ο Personalized recommendations are not neutral but based on bidding systems where advertisers pay to appear in a user's feed.

6. Amazon's Sponsored Products and Display Ads allow sellers to pay for visibility, impacting product exposure and forensic interpretation.

Ο A product can appear in search results not because a user searched for it, but because an advertiser paid for placement.

Ο The " Frequently Bought Together " and " Customers Also Bought " sections are influenced by paid sponsorships and algorithmic weighting, not purely organic trends.

Ο To properly assess forensic relevance, all Amazon ad data should be reviewed, including:
a) What sponsored products were displayed to this account?

b) What retargeting ads followed the user across platforms based on past activity?

c) Were certain product recommendations organic, or manipulated through paid placements?

d) Did Amazon's algorithm repeatedly push certain products based on prior engagement rather than active user searches?

7. Cart and Wishlist Data are an important part of forensic examination as it relates to Amazon.

Ο The addition, removal, or modification of items in a cart or wishlist provides insight into purchasing intent.

Ο Indecision and comparative shopping behaviors are common, and forensic analysis must account for all list interactions.

Ο Amazon's AI tracks wishlist and cart activity to refine recommendations and alter subsequent search results.

8. In his expert opinion, when evaluating the purchase or search of a product on Amazon as evidence, it is essential to ensure that it is presented in its full context rather than in isolation.

Ο Forensic best practices require examining broader user engagement trends rather than isolated transactions.

Ο A search or purchase cannot be evaluated without consideration of Amazon's Al-driven content curation and advertising models.

Ο Clickstream analysis, browsing history, and algorithmic reinforcement must be considered before attributing a specific intent to an individual search or purchase.

9. Many Amazon accounts, including the one in this case, are shared among family members, making it difficult to attribute a single purchase to one specific individual.

Ο Amazon does not differentiate between users within a shared account.

Ο Without analyzing full account activity logs, it is not possible to determine who conducted a specific search or made a purchase.

Ο Device usage history, login timestamps, and behavioral tracking data are critical to accurate forensic conclusions.

10. Obtaining and reviewing Amazon data prior to March 2022 is critical to the ability to draw conclusions or put context into any purchasing.

• Pre-March 2022 purchase and search data is necessary to establish historical buying patterns and determine whether a transaction was an anomaly or part of a long-term behavior trend.

004161

• Without earlier records, it is not possible to assess the evolution of search recommendations, AI influences, or external advertising impact over time.

11. The warrants in this case ask for extensive amounts of data and important categories of data, but the data produced by the State does not reflect the whole of the data requested or supposedly produced.

• The limited dataset does not include key forensic elements necessary for a comprehensive analysis, including:
a) Sponsored ad exposure records.

b) Algorithmic recommendation tracking.

c) Complete purchase and browsing history.

d) Cross-device usage logs and user attribution data.

• Without a full forensic dataset, conclusions drawn from the available information lack reliability and are inherently incomplete.
