FIRST APPELLATE DISTRICT

DIVISION ONE

THE PEOPLE, Plaintiff and Respondent, A156114 v. MATTHEW WIMER, (San Mateo County Super. Ct. No. 17NF008503) Defendant and Appellant.

California law provides that any person who knowingly distributes or exchanges obscene material involving children performing or simulating sex acts is guilty of a wobbler offense. (Pen. Code § 311.1, subd. (a).)1 When a person knowingly distributes or exchanges child pornography “for commercial consideration,” the offense is a felony punishable by a term of incarceration in state prison for two, three, or six years. (§ 311.2, subd. (b).) Matthew Wimer was convicted of four counts of distribution of child pornography for commercial consideration (§ 311.2, subd. (b)), and one count of possession of pornographic images of minors (§ 311.11, subd. (c)(1)), after he was found in possession of pornographic images and videos on computer files accessible to other users on a peer-to-peer sharing network. On appeal, Wimer contends that the trial court erred when it instructed the jury that the element of “commercial consideration” in section

1All further statutory references are to the Penal Code unless otherwise specified.

1 311.2, subdivision (b) may be established by an intent to trade in pornographic material with others, and that the evidence at trial was insufficient to support his proposed construction of this element. We agree that the trial court erred in its jury instruction and that this error necessitates a reversal of appellant’s convictions under section 311.2, subdivision (b). On remand, the People may elect to retry appellant on the section 311.2, subdivision (b) allegations, or to stand by Wimer’s conviction on the lesser included offense of distributing child pornography without commercial consideration (§ 311.1, subd. (a).) I. FACTUAL AND PROCEDURAL BACKGROUND A. The Prosecution Case In April and May 2017, Sergeant Christopher Servat of the San Francisco Police Department used an investigative software program to search the BitTorrent network for suspects distributing child pornography. As Sergeant Servat explained, BitTorrent is a peer-to-peer file sharing network that “is used to share, download, [and] distribute” “massive amounts of data” over the Internet, such as movies, videos, and music. The network is also used to distribute child pornography. To download and share files over a BitTorrent network, a user must install a BitTorrent software client on his or her computer and download a “torrent” from a torrent-search website. A torrent contains information about the target files, including their names, sizes, and cryptographic “hash values,” which are the numeric codes assigned to a file and considered “the DNA of a file.” The software client reads the torrent, finds the pieces of the target file from other BitTorrent users who have the same torrent, and downloads and assembles the pieces, producing a complete file. Law enforcement officers have identified many hash values that are associated

2 with child pornography and use specialized forensic software to detect and download these files from other peer-to-peer users to confirm the existence of such pornography. Typically, when a user downloads a file, it is saved in a default shared folder on one’s computer that is accessible to other BitTorrent users. A user can choose not to share files by actively disabling the access setting. If a user blocks others’ access to his or her collection of files, the user’s connection through the BitTorrent network will be slowed down. According to Sergeant Servat, it is “typically in a user[’s] . . . best interest to allow their files to be shared.” The software “wouldn’t work without sharing.” On April 18, 2017, Servat’s software program was alerted to a computer with a particular internet protocol (IP) address that had a shared folder containing multiple files with hash values of known or suspected child pornography. Over four days in 2017, Servat connected to that computer through BitTorrent and downloaded over 900 videos and images of child pornography. On April 18, Sergeant Servat downloaded approximately 209 images and videos depicting girls as young as 8 years old either posing nude in a sexually provocative manner or masturbating. On May 26, he downloaded a different torrent file that contained approximately 244 images and videos of girls appearing to be as young as six years old engaged in sexual conduct. The next day, Servat re-downloaded the same torrent file which contained 244 images and videos of child pornography. On May 28, Servat downloaded the same torrent file, which now had 217 files of child pornography. Using the target computer’s IP address, Sergeant Servat determined that appellant was the Internet subscriber for that address. Servat executed a search warrant of appellant’s residence where officers found 817 images

3 and 10 videos of child pornography on one of appellant’s computers, a Sony laptop. BitTorrent and encryption programs had been installed on appellant’s other computer, a Hewlett-Packard (HP) laptop. A digital forensic examiner found evidence that torrent files containing child pornography had been downloaded to the HP laptop at some point, including the files that appellant had shared with Sergeant Servat. He also found a large encrypted file on the laptop approximately 100 gigabytes in size, capable of holding 50,000 images. Appellant’s search history on the Google search engine was also admitted into evidence, and included terms such as “sad girls spanked TGP,” “rape TGP,” “cruel TGP,” “microbikini preteen,” “microbikini child,” “microbikini baby,” and “amateur preteens.” Other child-pornography- related search terms had been bookmarked in a web browser. B. The Defense Case Appellant testified he had approximately 25 years of experience in computer programming. He spent about 16 hours a day, seven days a week, on his computer. Appellant was well versed in peer-to-peer networks. He admitted he used a BitTorrent network to download child pornography. When appellant installed BitTorrent on his computer, he was aware that in participating in a peer-to-peer network, “with the ability to download comes the ability to upload.” He knew that his software client’s settings defaulted to enable other users to access the contents of his shared folder, but claimed he did not intend to share any of the child pornography and forgot to turn off the default setting. Appellant admitted he had obtained hundreds of thousands of images of child pornography. But he claimed he had downloaded the material as part of a project to develop an algorithm that would determine if individuals

4 in pornographic images were underage, similar to facial recognition. Appellant testified that this project could help law enforcement and other “people [who] are actually being harmed by the production of this type of material.” He conceded, however, that he did not mention the project to the police after his arrest and had initially denied searching for and intentionally downloading child pornography. C. Jury Verdict The trial court instructed the jury that to find appellant guilty of section 311.2, subdivision (b), “the People must prove that: [¶] 1. The defendant distributed or exchanged obscene matter with someone else; [¶] 2. When the defendant acted, he knew the character of the matter; [¶] 3. When the defendant acted, he knew that the matter showed a person under the age of 18 years who was personally participating in or simulating sexual conduct; AND [¶] 4.
