In the U.S., the Federal Trade Commission is currently investigating Facebook's failure to prevent the Cambridge Analytica data breach. Facebook expects a $5 billion fine for violating its consent decree with the FTC in which Facebook agreed not to share users' personal data without their consent. 31 If the FTC issues a $5 billion fine against Facebook, it would be the largest penalty a U.S. regulator has ever levied against a technology company. 32 The investigation may also result in structural remedies, including a requirement that Facebook create new positions within the company devoted to strengthening user privacy and company compliance overseen by an independent committee established by the FTC. Commissioners, however, disagree over whether Facebook CEO Mark Zuckerberg should be held personally liable for any future violations. 33 Some argue, however, that individual enforcement cases cannot be a substitute for comprehensive regulation. 34
