Ralf Gross infiltrated animal liberation, environmentalist, anti-repression, and anti-fascist groups in Germany. He worked for the police. He attended events and demonstrations, and participated in actions. On one occasion, the morning after an arson attack, he called an activist and asked if he had slept well, presumably to determine whether he had participated in the attack. He carried out the infiltration under his real name.

He was identified because:

  • He exhibited suspicious behavior, which led activists to suspect him. For example:
    • He had meat in his refrigerator and kept dogs in a kennel at his home, which was suspicious considering he participated in animal liberation groups.
    • He reacted suspiciously when someone asked to borrow his laptop.
  • Activists gained access to his email account and discovered that he had sent suspicious emails.
  • Activists gained access to his Facebook account and found private messages in which he expressed disdain for animal liberation actions.
  • In an attempt to confirm that he was an infiltrator, activists told him about a fake clandestine action, and later recorded a phone conversation in his car during which he gave information about the action to an unknown person.
  • When confronted with the accusation that he was a spy, he tried to deny it, but he was not convincing at all.

He had been involved in activist groups for years before being recruited by the Federal Bureau of Investigation (FBI). During the RNC, he wore a recording device hidden in his belt.
