Shaffer Security Group (@ShafferGroup) — X Posts

@ShafferGroup is the corporate X account of Shaffer Security Group (SSG), founded by Greg Shaffer, described in reporting as a former FBI agent. It is not a citizen investigator — it is a first-party participant whose since-deleted posts are preserved as evidence of the dispute over which firm held the TPUSA security contract on September 10, 2025.

Claims from X posts​

  • September 26, 2025, 11:33 PM (deleted within hours, 13 views at capture) — posted that the security firm contracted by TPUSA when Charlie Kirk was killed "want[s] to remain in the shadows while my firm takes blame," stating "SSG was not and had not been affiliated or contracted to do security for TPUSA since 2022," with the Texas business record for Rockhouse Integrity Group LLC attached. (Capture)
  • September 27, 2025 — a second post: "My firm was NOT in Utah on 9/10/2025... The private security firm, hiding in the shadows, not taking responsibility for their actions is Rockhouse Integrity Group, dba: Integrity Security Solutions." The attached record lists Brian Harpole as registered agent and manager. (Capture)
  • The corporate registration core is a public record and independently checkable; the characterization of the other firm is one party's view in what reporting describes as a longstanding business dispute between former colleagues. Greg Shaffer repeated the substance to Headline USA.
  • The account's April 2017 join date was separately captured to authenticate the deleted posts. (Capture)

Investigative value​

The deleted posts are the clearest first-party statement on which firm was actually responsible for Kirk's private security at UVU — a question central to the security-failure record. That the posts were deleted within hours is itself part of the record. No wrongdoing by Brian Harpole, Integrity Security Solutions, SSG, or anyone else named is established by these documents.

The clearest technical explainer of what the ATF's inconclusive finding actually means: the jacket fragment was suitable for comparison, the lead was not, and the examination neither identified nor excluded the recovered rifle. It is the discipline check that stops both camps over-reading one word.

Within hours of the shooting this account posted that N888KG left Provo, dropped off ADS-B thirty minutes out, and came back. The capture predates the owner's pre-scheduled-round-trip explanation, so readers can see the sequence: observation first, explanation afterwards.

The capability half of the Israel argument — the 2024 supply-chain pager operation, PETN inside device batteries, and the reach that demonstrates. This site flags on every page that capability in another theatre is not evidence of action in Utah, which is why the account is quoted rather than endorsed.

A widely recirculated sniper analysis that contradicts both camps at once: not a .30-06, fired from slightly behind Charlie's right, and with a visible exit wound. The clearest reminder that early video-based ballistics readings diverge sharply and none of them replaces the sealed medical exam.

Shaffer Security Group (SSG)

The firm that guarded earlier Kirk stops, founded by a reported twenty-year FBI veteran, and reportedly not on the detail that day. A since-deleted post from its own account is the document the whole vendor-switch argument turns on.

In the weeks before September 10 the court, the Salt Lake FBI field office and the treating hospital each changed leadership. Timing alone proves nothing, which is why the page is a timeline and an open question.
