Obtaining and preserving CCTV footage for your defence

Storage is often the first urgent step

Camera systems can automatically overwrite recordings. The retention period depends on the system, purpose and applicable rules. There is no reliable general rule that all images remain available for exactly four weeks. The Dutch Data Protection Authority describes the privacy framework surrounding camera use; this does not guarantee that a specific file is still present. A targeted request for preservation must therefore be discussed as quickly as possible once it is clear that a recording may be relevant. (Dutch Data Protection Authority describes the privacy framework surrounding camera use)

Our editorial analysis separates urgency from evidence appreciation. First it is investigated whether material still exists and can be preserved. It can then be assessed what it shows and how it legally becomes available. Waiting until you have the complete file could mean an irreparable loss. At the same time, urgent does not give permission to enter an account or copy a system itself. The lawyer can choose an appropriate preservation and investigation route and have the receipt of a request recorded.

A concrete research question makes the request usable

The sentence that images prove your innocence is often too general. An administrator or researcher must know which time period and which camera are meant. Also describe what decision the images can influence: were you in a certain place, who was driving, what action preceded it or was there a visible obstacle? A targeted question makes it possible to search for relevant material without unnecessarily requesting large amounts of personal data from others.

Include a wide enough time period to accommodate context and possible clock drift. Explain what the time estimate is based on, for example a receipt or your own message. Do not present an approximate time as exact system data. At multiple entrances or routes, it must be clear which camera may have had a view. A request can also specify the surrounding minutes needed to understand a fragment. The practical quality lies in recognizability and relevance, not in the length of a general legal letter.

Who has control over the recording?

A camera can belong to a store, employer, home resident or government agency. The visible camera does not always tell who is responsible for the file or who can grant access. Therefore, ask for the administrator and the purpose of the system via an appropriate route. The difference is relevant for privacy rules, retention periods and the way in which police or defense can obtain material. A receptionist can accept a request without being authorized to independently provide all images.

Do not approach a potential witness or person involved in an intimidating manner. A neutral retention request via the lawyer can make it clear that it concerns retention for a specific case. Do not share more file information than necessary. If the administrator says that images do not exist, ask which camera or period was examined and how that was determined. A missing file may be an actual boundary; it is not always proof that someone removed material to prejudice the defense.

A privacy request and a criminal law request differ

An access request under privacy rules does not constitute an unlimited right to all recordings of others. Third party interests and exceptions may be significant. The applicable data regulations may also differ for police data. For the criminal case, there are also options to submit investigation wishes and requests for procedural documents. The Code of Criminal Procedure provides the procedural framework; the appropriate route depends on where the statues are located and what you need. (Code of Criminal Procedure)

Therefore, let the lawyer choose between retention, inspection, addition to the file or further investigation, possibly in combination. A request to the wrong party can take time while direct deposit continues. Ask for confirmation of receipt and record exactly what was requested. A general complaint about privacy does not automatically provide the evidence you need in the criminal case. Conversely, a criminal interest does not give license to ignore all privacy interests of other filmed persons.

Images in the file and images that are described only

An official report can describe what an officer saw on images. That is not the same as the recording itself being accessible to the defense. Sometimes stills have been added or a selection has been made. Ask which files are actually available and how they relate to the description. Requesting the police explanation about case documents helps recognize the route, but the specific request must state why the material is relevant to the defense. (Request police explanations about case documents)

Check whether the description reflects an observation or already contains an interpretation. Words such as threatening, conscious or the same person may require further substantiation. Images can support an interpretation, but also have limits due to resolution, angle or missing sound. Don't just ask for more material because that would always be better. Indicate which control becomes possible: the recognition, sequence or duration of an action. In this way, a request is in line with the evidentiary reasoning that is actually used in the case.

Origin and completeness make a file verifiable

An original export file may contain information that is missing from a screen capture. Sequential fragments, file times and data about the export may also be relevant. This does not mean that every copy is worthless, but it does mean that its origin must be recorded. Who provided the file, what system does it come from and has it been edited? Keep received files in their original form and make a separate copy for your own use.

Do not cut or improve material as if the edit were the original. An enlarged or slowed down version can be useful for explanation if it is clear how it was created and the original file is preserved. Also indicate boundaries: sharpening does not really reveal all the missing details. When authenticity or technical interpretation is central, an expert question may be necessary. The relevant test is what can be responsibly inferred from the available material, not how convincing an edited presentation looks.

A timestamp may differ from the actual time

Camera systems may be positioned incorrectly or handle summer and winter time differently. A visible time is therefore a fact that must be checked, not an automatic truth. Where possible, compare with an independently known moment, such as a transaction or other registration. Indicate the size of a possible deviation and how it was determined. A shift chosen afterwards to make the image fit a story is not a reliable reconstruction.

Missing between fragments and differences in playback speed also deserve attention. An event may appear shorter or longer depending on the export and player. The defense does not have to explain every technical detail itself, but can ask specific questions about completeness and synchronization. This is especially important when two cameras or camera images and phone data are combined. A timeline that places several sources at the same minute without control can give a false sense of certainty about the order of actions.

Relevant evidence does not have to be made public

A suspect may feel a strong need to post images online to convince others. This can violate the privacy of bystanders, influence witnesses and complicate the investigation. The appropriate place for a request for evidence is usually criminal proceedings through legal aid. Share files privately and ask who should receive them. The ability to view a recording does not automatically grant permission for wide distribution.

Additional safeguards may be required for sensitive material. Think of children, medical situations or private spaces. The lawful acquisition and use of digital data also requires an appropriate framework; the Supreme Court has emphasized the importance of demarcation in data research, although that ruling does not regard every camera request as having the same authority. Therefore, apply legal rules to the actual action. A reference to privacy may require a specific assessment, but relevant exculpatory material should be ignored. (Supreme Court has emphasized the importance of demarcation in data research)

Fictional example: the camera at a second exit

A fictitious visitor is accused of involvement in an incident at an entrance. He says he left through a different exit at that point. The first reaction is that the main camera shows nothing. That doesn't answer the question about the second exit. A targeted request states the other location, the likely walking route and a time slot that takes into account the source of the time estimate.

The lawyer asks in a timely manner whether that material still exists and can be retained. Only then is it investigated whether the image offers sufficient recognition or a relevant indication of time. The example does not promise that a recording will solve the case: someone may be out of the picture or the quality may be insufficient. The added value is that the research question does not disappear because only the best-known camera is examined. A targeted question can make a gap visible without presenting the desired conclusion as a fact.

A retention request with the correct data

Use the items below to consult with the attorney. A request may request preservation without requiring that all images be immediately delivered to you personally. Let the receiving party know how to contact you safely and ask for confirmation. Avoid unnecessary details about other people involved. The overview is intended to make relevant material recognizable in a timely manner, while the lawful provision is assessed separately.

• Location: address, entrance, route and recognizable camera or responsible manager.
• Time: date, time period, source of the estimate and possible clock deviation.
• Relevance: which concrete action, presence or sequence must be investigated.
• Preservation: original files, surrounding context and available export data.
• Status: does the material still exist, who keeps it and is there a risk of direct transfer?
• Route: lawyer, investigator or competent authority that can request access or addition.
• Log: sent request, receipt, response and responsible next step.
