Shaffer Security Group (SSG)
Shaffer Security Group (SSG) — X handle @ShafferGroup, a security firm founded by Greg Shaffer, described in reporting as a former (twenty-year) FBI agent — is the vendor that reportedly provided private protection for Charlie Kirk and TPUSA on earlier tour stops. SSG has publicly stated it was not the firm on the detail at UVU on September 10, 2025; the firm on stage that day was reportedly Integrity Security Solutions (Rockhouse Integrity Group LLC), founded by former SSG employee Brian Harpole.

The deleted @ShafferGroup post
According to @alleytopfiles (July 18, 2026), who published the screenshot from their files, a since-deleted post from @ShafferGroup (timestamped 11:33 PM, 9/26/25) stated, in SSG's own words:
"This is the security firm contracted by TPUSA for security when Charlie Kirk was killed. They want to remain in the shadows while my firm takes blame. SSG was not & had not been affiliated or contracted to do security for TPUSA since 2022!"
The post displayed a Texas business record for the firm SSG was pointing to:
- Rockhouse Integrity Group LLC (DBA Integrity Security Solutions)
- Texas Tax ID 32089791597; File Number 0805052578
- Incorporated May 9, 2023 in Texas as a Texas Limited Liability Company; status Active
- Registered Agent / Manager: Brian Harpole, 931 Fortner Rd, Lantana, TX 76226
- Governing Agency: Texas Secretary of State
This is SSG's public characterization of who was contracted — an attributed claim in a business dispute, not a court finding.
Greg Shaffer's Headline USA statements
Headline USA excerpt on Shaffer's phone statements. Source: @alleytopfiles on X, July 18, 2026.
After the @ShafferGroup post was deleted, Headline USA reported that SSG's owner, described as former FBI agent Greg Shaffer, reiterated the same information by phone. The excerpt shared by @alleytopfiles attributes these statements to Shaffer:
- "The individuals who work for that company [Integrity Security Solutions] were the ones on the stage."
- Integrity founder Brian Harpole and TPUSA security director Dan Flood both "used to work with him until they 'stabbed [him] in the back.'"
- "Dan Flood headed up security for Turning Point USA, and Brian Harpole is his best friend. Brian worked for me for seven years, and then Brian started his own company..."
These are Shaffer's characterizations of a business dispute reported by a media outlet. They are not adjudicated findings, and nothing here establishes criminal intent by Harpole, Flood, TPUSA, or SSG.
Why researchers track SSG
The @alleytopfiles post frames an open question that citizen investigators keep returning to: is Justin Davis — a name linked online to the detail — currently with SSG or with Integrity? More broadly, the SSG-vs-Integrity split matters because:
- It defines who was actually accountable for the perimeter and rooftop plan at UVU.
- It documents a vendor transition (SSG era through ~2022, then Harpole/Flood spinning out Integrity) that shapes the "who controlled the bubble?" debate.
- Shaffer's former-FBI background is cited both by those alleging deeper agency ties and by those countering foreign-intelligence theories — the master file notes no foreign nationals documented on SSG rosters, which cuts against some Mossad-link claims that remain unproven regardless.
Disambiguation: Shaffer vs. Schaffer
The master file distinguishes two similar names — see Greg Shaffer for the full note. In short: Greg Shaffer is the interview subject and @ShafferGroup owner; Greg Schaffer is referenced as a twenty-year FBI agent tied to SSG's founding with Brian Harpole.
Open questions
- Does Justin Davis currently work for SSG or Integrity Security Solutions? (the direct question raised by @alleytopfiles)
- If SSG last worked with TPUSA in 2022, why did eyewitness footage reportedly show familiar "white-shirt" agents at the 2025 event?
- What records (contracts, filings) would confirm the SSG → Integrity transition timeline?
