Ethical and Legal Considerations
Blurring license plates isn't just ethical in many jurisdictions, it's legally required. Always consider:
GDPR/CCPA compliance
FOIA exemptions
HIPAA (for ambulance/care vehicle footage)
Canada (PIPEDA)
Avoid over-redaction (which reduces footage utility) and under-redaction (which can expose data).
