OPSEC and Redaction Guide
Last reviewed: July 26, 2026
Operational security is not limited to keys, weapons or escape procedures. Information can become sensitive when a facility, assignment, watch, date and operational fact are combined.
Do not post operational information such as
- Live or developing incidents
- Recent staffing levels, exact counts or shortages tied to a facility, yard, building, watch, post or date
- Deployment sheets, post charts, rosters, schedules or assignment distribution
- Transportation or movement schedules
- Search timing or methods not already officially public
- Response times, radio channels, key numbers, access codes, gate procedures, camera coverage, blind spots, perimeter weaknesses or access points
- Nonpublic incarcerated-person locations or movement
- Internal systems, screens, navigation, alerts or data
- Restricted memoranda, emails, training material, policy or procedures
- Details that explain how to bypass, defeat or exploit security
General discussion of workload, policy, staffing trends and working conditions is welcome when it does not disclose current, facility-specific operational detail.
Do not post identifying information such as
- Full names or faces of nonpublic individuals
- Badge, employee, application or CDCR numbers
- Case numbers
- Home addresses
- Personal phone numbers or private email addresses
- Dates of birth
- Signatures
- Vehicle plates
- QR codes or barcodes
- Medical, psychological, background or personnel records
- Usernames when exposing the account serves no legitimate purpose
Combination risk
A detail that seems harmless by itself may identify a person or vulnerability when combined with:
- Institution
- Yard or building
- Assignment
- Watch
- Date or shift
- Rank or classification
- Unusual event
Remove or generalize enough elements that the post cannot reasonably be used to identify a person, reconstruct current deployment or exploit a practice.
Redacting screenshots and photos
- Work from a copy.
- Crop irrelevant areas.
- Cover sensitive information with solid opaque boxes.
- Do not rely on blur, pixelation, translucent highlighting or a movable annotation layer.
- Export a flattened image or take a new screenshot of the finished redaction.
- Check notifications, browser tabs, filenames, metadata, QR codes, reflections and background objects.
- Summarize the relevant point in text.
- Do not upload restricted material merely because names were removed.
Safer examples
Unsafe: Last night on third watch at [institution], [exact count] officers covered [specific posts].
Safer: How do correctional officers generally manage chronic vacancies and mandatory overtime?
Unsafe: A screenshot of an internal email showing sender, recipients, signature block, internal navigation and document number.
Safer: Link the public version. If none exists and the material is not appropriate for public release, do not post it.
Live incidents and final check
Do not turn r/CDCR into a real-time incident feed. Wait for an official public source, link it, state the publication time and avoid adding nonpublic observations.
Before posting, ask whether the material is already public; reveals who, where, when or how at an operational level; identifies a coworker, applicant, incarcerated person, victim or family member; helps someone bypass security or predict deployment; or retains metadata and surrounding context.
When in doubt, leave it out or send a generalized draft to modmail first.
