Doubts are being pushed about the official story of Charlie Kirk's killing, which is bad news for prosecutors trying to convict Tyler Robinson.

• Within minutes of the shooting, a Turning Point USA audio-visual staffer pulled the memory card from the one camera pointed at the back of Kirk's head.
• He skipped the other cameras, stood on the bloodied chair to reach gear, and looked around nervously before pocketing the card and texting someone.
• Investigators were reportedly given only Google links and a flash drive, never the original memory cards, which leaves room for questions about tampering.
• The explanations offered for the delay — sparing Kirk's widow, not knowing how to send big files, fear of Google hacking — do not line up with what came out at the preliminary hearing.
• Nobody has explained where the original cards went, with a vague claim they were handed to the FBI even though this is a state case.

Outlook: Expect growing pressure on prosecutors and the FBI to account for the missing original footage before Robinson's case moves forward.
