This document excerpt details the defense's ongoing efforts in July 2007 to halt a federal investigation into Epstein and prevent the government from obtaining computer equipment, including sending letters to the USAO. Concurrently, CEOS endorsed Villafaña's legal analysis and proposed charges, with CEOS Chief Oosterbaan finding the defense's arguments unpersuasive and offering CEOS's assistance for the prosecution. The document also references a Non-Prosecution Agreement (NPA) and the removal of computer equipment from Epstein's home.

This document details the rationale behind Alexander Acosta's decision to pursue a state-based, pre-charge disposition in the Jeffrey Epstein case instead of a federal trial. Acosta explained to the Office of Professional Responsibility (OPR) that his decision was based on federalism concerns, the weakness of the case, and a desire to act as a 'backstop' to the state prosecution, ensuring Epstein was registered as a sex offender. This contrasts with the views of other prosecutors, like Villafaña, who believed strongly in the federal case and wanted to proceed to trial.

This document is a page from a legal filing, likely an investigative report by the Office of Professional Responsibility (OPR), detailing interviews about the failure to notify victims before a Non-Prosecution Agreement (NPA) was signed. It presents conflicting accounts from key figures like Sloman, Villafaña, and Acosta regarding the USAO's policy on victim consultation under the CVRA for pre-charge resolutions. The text highlights internal disagreement and confusion over the legal obligations to victims, with CEOS Chief Oosterbaan disagreeing with the USAO's stance but not finding it to be an abuse of discretion.
