| Field | Value |
|---|---|
| Full Name | Greg Shaffer |
| Affiliation | Connected to Integrity Security Solutions; founder history with Shaffer Security Group |
| Status | Alive |
| Evidence basis | Public interview + AP reporting |
Greg Shaffer is a figure connected to Integrity Security Solutions and to the prior Shaffer Security Group (SSG) vendor that guarded Charlie Kirk on earlier tour stops. He has spoken publicly about how Integrity came to take the UVU assignment.
"Stabbed in the back" interview
According to the investigation file, Shaffer gave a public interview providing "new details about how Integrity Security Solutions came to guard Kirk in the first place." In that interview he said he was "stabbed in the back."
That phrase is his characterization of a business dispute — not a legal finding about TPUSA, Integrity, or any other party.
Last-minute rehiring — AP report
Shaffer's account aligns with a September 2025 Associated Press report describing last-minute rehiring for "specialized security." Researchers cite this timing when asking why the UVU setup was described as lighter than prior events and why no bodycams were on the detail.
Open questions about process are not proof of intentional sabotage.
Shaffer vs. Schaffer — disambiguation
The master file distinguishes:
| Name | Role discussed |
|---|---|
| Greg Shaffer | Interview subject tied to Integrity coming to guard Kirk |
| Greg Schaffer | Twenty-year FBI agent; SSG founder with Brian Harpole; LinkedIn |
Shaffer stated SSG had not worked with TPUSA since 2022, yet eyewitness footage reportedly shows familiar white-shirt agents from earlier Kirk events. That tension is a transparency question documented on Integrity Security Solutions.
SSG background (context)
The file describes SSG as recruiting U.S. Tier 1 operators with FBI-aligned training. It notes no foreign nationals documented on SSG rosters — countering some online Mossad-link theories, which remain unproven regardless.
Post-incident, the FBI / Utah AG probe reference includes SSG subcontractors in obstruction questions (scene cleanup, chain of custody). That scope is investigative, not an adjudicated charge.
Citizen Investigator Claims on X
:::caution Legal Disclaimer Nothing on this page constitutes a finding of wrongdoing by any named security professional. Allegations from public commentary are unproven. :::
- Brian Harpole (ISS / contracted security leadership in public discussion) is central to “two sounds,” rooftop-text, and Fort Huachuca threads; he has pursued defamation claims against Candace Owens and Mitchell Snow over Huachuca allegations (reported Apr 2026).
- Competing posts cite travel receipts placing Harpole in the Dallas area during parts of Sept 8–9; community notes note residual morning-window ambiguity — not a site finding either way.
- Other security names on this site (Dan Flood, Bobby Harpole, Greg Shaffer, etc.) appear in SUV-response, Signal, and chain-of-command discussions; intentional enabling of a killing is not established and must not be stated as fact.
- Page focus: Greg Shaffer. See Security Team for structure.
