A private investigator is conducting surveillance and observes a minor offense unrelated to their investigation. According to the PSISA Code of Conduct (O. Reg. 363/07), what is the appropriate action?

1. Act with integrity and honesty, but it's generally not their duty to enforce laws or intervene in unrelated minor offenses.
2. Document the offense and report it to the Registrar.
3. Immediately apprehend the offender and contact local police.
4. Ignore the offense completely, as it's outside their scope.
