The same day, San Francisco Sheriff Paul Miyamoto said his office had conducted a child sex sting operation resulting in the arrest of five men. Hansen, who could not be reached for comment, reached out to the San Francisco Sheriff’s Department to take part in the sting, the department said. The Sheriff’s Department, which characterized the operation as proactive policing, does far less street-level enforcement than its counterpart, the San Francisco Police Department. A Florida sheriff’s department that invites Hansen to its biannual child sex stings said it sent a sergeant to help its San Francisco counterpart, which has limited experience conducting such operations. San Francisco Sheriff Paul Miyamoto and District Attorney Brooke Jenkins did not mention Wednesday that Hansen was involved in the sting.
