For example, Wesley David Gilreath. BTW, not a good idea to leave unencrypted cell phones full of CP on the bus, unless you're TRYING to get busted:
Gilreath previously told FBI agents he “wanted the white race to win at life” and had information about Oklahoma City bomber Timothy McVeigh and the New Zealand mosque shooting on his phone, in addition to thousands of images and videos containing child pornography, when the phone was found by RTD workers on a bus in Boulder last May 31.
Those workers turned the phone over to Boulder police, who then handed it over to the FBI last year. According to the U.S. Attorney’s Office, the phone had more than 12,000 images and 200 videos containing child pornography and also used his phone to try to find more.
Agents arrested Gilreath last July 31 and searched his home the next day. They discovered a thumb drive containing nearly 25,000 images and videos that showed child pornography, and another thumb drive with an additional 6,000 photos and videos, the U.S. Attorney’s Office said. The videos and photos also depicted toddlers and infants.
