Zach Costello Defends Open Investigation Into Charlie Kirk Assassination After Heated Paramount Tactical Debate

Zach Costello breaks down his heated discussion with Gary Melton on Paramount Tactical, defending the need for an open-source investigation into the Charlie Kirk assassination. Costello argues there is reasonable doubt that Tyler Robinson acted alone or fired the shot, citing inconsistencies in charging documents, statements from Robinson's family members at court hearings, and a pattern of government dishonesty. He pushes back against critics who label alternative theories as conspiracy, insisting all responsible parties must be found and held accountable regardless of the consequences.

Defending the Open-Source Investigation

Zach Costello opens by clarifying his position following a lengthy discussion with Gary Melton on the Paramount Tactical YouTube channel. The conversation, which lasted over three hours, centered on the Charlie Kirk assassination and the evidence surrounding Tyler Robinson. Costello emphasizes that he is not a debater but someone seeking truth through discussion, even when conversations become tense or heated.

Costello states his fundamental disagreement with Melton: while Melton believes there is overwhelming evidence of Tyler Robinson's guilt, Costello argues there is sufficient evidence to establish reasonable doubt that Robinson acted alone or even took the shot from the roof location authorities claim. He supports a decentralized, open-source investigation to ensure public pressure is applied to investigative authorities who have not proven themselves competent or honest.

Reasonable Doubt and Investigative Failures

Costello explains that his skepticism stems from working backwards from a distrust of state and federal authorities, whose record of incompetence and dishonesty—citing COVID, the lab leak theory, January 6th, the 2020 election, and Butler, Pennsylvania—causes them not to be trusted. He supports continued investigation to ensure this doesn't become another JFK-style conspiracy case.

His position is not attached to any specific conclusion but rather to finding all responsible parties so they can be held accountable and true justice served. He wants nothing withheld and the truth regardless of consequences or who it implicates. Costello believes this open-source inquiry and discernment of alternative theories is needed to apply required public pressure on investigative authorities.

Free Speech and Defending Good Faith Researchers

Costello positions himself as a free speech absolutist and defender of individuals conducting research and investigating leads in good faith. He lists researchers including Candace Owens, Baron Coleman, Ian Carroll, Chris Martinson, Blake Bednarz, and others who have been looking into the Charlie Kirk case. He strongly opposes the shutdown, silencing, or labeling of any alternative argument or dissenter as evil, lunatic, or conspiracy theorist.

He argues that these independent investigators have historically been proven correct through examples like COVID, the lab leak theory, FBI presence on January 6th, and the Thomas Crooks investigation in Butler, Pennsylvania. Costello questions why we should now simply trust the FBI and state authorities when they have repeatedly misled the public.

Bombshell Information About Tyler Robinson's Family

During the conversation with Melton, bombshell information emerged in real time about what Tyler Robinson's family thinks about the case. When challenged about Robinson's parents believing he was guilty, Costello cited the account from Brandi and Billie who attended the January 16th court hearing and spoke directly with Robinson's family members.

During the livestream, Blake Bednarz, who was watching, texted Brandy asking for clarification. Brandy responded that they were sitting in the courtroom when a family member briefly spoke to them and said only 2% of what you hear in the media is true about Tyler and they don't think he was capable of doing something like this. When asked if this family member was sitting with Tyler's parents, Brandy confirmed yes, though she couldn't reveal who it was for privacy reasons. She indicated the same belief was likely shared by all family members present.

This information is critically important because it puts into doubt the charging documents, which are the only evidence currently available. The charging documents rely heavily on the claim that Robinson's parents identified him from still shots of an individual in black clothing walking up a stairwell. If the family does not believe the narrative, this undermines a key foundation of the state's case.

No DNA Evidence Places Robinson on the Roof

Costello emphasizes a crucial point that many overlook: the charging documents contain no evidence that places Tyler Robinson on the roof. There is no DNA evidence connecting Robinson to the roof location. The only piece of evidence allegedly containing Robinson's DNA was a screwdriver, but this is not included in the charging documents and remains hearsay.

The video evidence shows an individual in black climbing over a fence and army crawling to a spot, but then the footage goes dark. There is no video of the actual shot being taken. The footage resumes showing an individual running across the roof afterward. Nothing in this video definitively proves that individual is Tyler Robinson. The state's case relies on still shots from a stairwell that parents allegedly identified as looking like their son, but this testimony is now in question given the family's statements at the court hearing.

Exposing Hypocrisy on Erika Kirk's Dishonesty

One of the most frustrating moments in the conversation came when Costello attempted to get Melton to acknowledge that Erika Kirk was dishonest about her dating history. On CBS with Bari Weiss, Erica told a young girl asking about dating in New York City that in the five years leading up to meeting Charlie Kirk, she did not date in New York City and did not participate in the drinking scene.

Costello pointed out that Erica appeared on the 2018 Bravo reality show Summer House, where she went on a date with cast member Jordan Verroi at a New York City rooftop bar and was shown drinking alcohol. When pressed on whether this constituted dishonesty, Melton offered various explanations and spin rather than acknowledging the clear contradiction.

The situation became more frustrating when Melton's producer displayed definitions of lying and statistics about how often people lie. Costello expressed exasperation, explaining he wasn't trying to trap anyone with semantics but simply asking whether a public figure conducting a media tour, who just took over a powerful political organization, should be held accountable for blatantly lying, especially when those questions were pre-planned and she had time to prepare honest answers.

The Circumstantial Evidence Web

Costello explains his approach to the evidence as building a circumstantial evidence web. While each individual irregularity might be easy to dismiss on its own, when you have multiple data points—one here, one here, one here—it creates a web that provides reasonable doubt against the state's case. This is why he brings up various examples and theories: to justify his position and demonstrate it's not based on unfounded speculation.

He acknowledges that some theories have been put forward that he himself has dismissed, and he understands others have dismissed theories he still considers. But the overall pattern of irregularities, inconsistencies, and unanswered questions creates legitimate justification for alternative narratives. The burden of proof remains on the state to prove beyond reasonable doubt that Tyler Robinson acted alone and took the shot from that roof location.

Moving Forward in Truth

Costello concludes by reiterating his commitment to truth above all else. He states he is subject to truth, not determining what truth is. If the state can prove beyond reasonable doubt at trial that Tyler Robinson acted alone and took that shot, he will accept it. He emphasizes that he is not married to any specific conclusion but to finding and accepting truth regardless of where it leads.

He explains that unification and moving forward as a country requires living in truth. When aligned with truth—which means being aligned with God and reality—individuals, families, organizations, and nations can move upward toward their highest potential. A nation and life built on lies crumbles. This is why the Charlie Kirk investigation matters so much: knowing the full truth allows society to move forward and upward toward life in full.

Costello announces he will continue having difficult conversations with those who disagree, noting that after conversations with Andrew Wilson and Gary Melton, he is actually more open-minded and considering additional theories about what happened that day. He remains committed to defending good faith researchers and investigators while opposing anyone who knowingly puts out false information or seeks to mislead.
