Are Videos Admissible in Court?
In today’s digital age, people are recording every moment of their lives with high-definition cameras. When this takes place, law enforcement and prosecutors can use the footage to investigate and prosecute criminal cases more efficiently.
However, it is essential to remember that video evidence can be falsified or even deep-faked. Therefore, any video evidence presented in court must not have been altered in any way before being entered into evidence.
Eyewitness Authentication
Eyewitnesses are essential in the justice system and often asked to identify suspects. Their purpose is to shed light on who committed a crime and seek justice, yet despite their best efforts witnesses can make mistakes when selecting or eliminating suspects.
Errors can range in severity from a minor misunderstand or oversight to being highly consequential and harmful. Indeed, these mistakes have been linked to many wrongful convictions and false identifications in the United States.
Criminal scientists have devised several methods to prevent misidentifications, including photo arrays and photo-spreads – a technique in which six or more photographs are displayed to an eyewitness at once. These tools aim to make it easier for eyewitnesses to accurately select or eliminate suspects (see Box).
Research has revealed that witnesses often focus on certain characteristics of an alleged perpetrator, such as his hair color, facial features, height or skin tone. Furthermore, they may ignore other features similar to but not identical to them.
Criminologists have observed that eyewitnesses are susceptible to inadvertent cues and reactions which could cause them to select the wrong person. This includes refusing to accept that the perpetrator may not be in the lineup or feeling pressured into selecting someone from photospread.
Therefore, these procedures should be conducted under stringent conditions to avoid witnesses mistakenly identifying the wrong suspect. Furthermore, the witness should be informed that while it is possible that the actual perpetrator may or may not be in the line-up or photospread, the investigation will proceed regardless of whether an identification is made.
Research into eyewitness identification is an extensive and ongoing endeavor, with much published. It has helped us gain a better insight into what causes misidentification among eyewitnesses, as well as recommending policies for combatting this error. Nonetheless, further study is necessary in this field of forensic psychology to better comprehend why and how these mistakes occur, and how they can be prevented.
Pictorial Authentication
In court, photographic evidence is typically introduced as supporting evidence for a witness’ testimony. If this testimony supports the finding that the image evidence “fairly and accurately portrays” their impression of the subject matter of the photograph, then it can be accepted into evidence.
However, when there is no witness who can testify as to how a picture was taken, courts rely on evidence of surrounding circumstances. These can include various elements. For instance, if someone can verify they were near the crime scene when the picture was taken, that evidence can be used in support of its authenticity.
Another key element in authenticating digital photographs is using forensic software to examine them. This allows law enforcement officers to detect any alteration to the photos as well as any loss in quality that might result when an image is copied or cloned with a digital camera.
For instance, Pictorial Authentication (Picture Detection), a free program available online, can be used to detect whether an image has been altered or edited by unskilled technicians. This issue arises frequently during criminal investigations when investigators lack access to the original source of an image.
In addition to its tamper detection feature, PICTURE Detection software can log and document any modifications made to a digital photograph after it has been taken, such as movement or changes in lighting. This information is essential for establishing the authenticity of image evidence, along with any video produced during an investigation.
North Carolina requires a specific form of authentication for all photographic evidence brought into court, as outlined in Rule 901(a). This requirement states that “evidence must be sufficient to support a finding that the matter in dispute is what its proponent claims.”
Chain of Custody
Chain of custody is an essential process to document and preserve all evidence in a legal case. It involves recording when and where something was collected, how it was handled, stored, and transferred – helping avoid any potential issues with validity of that evidence or its ability to be used in court. This helps safeguard against potential legal disputes over its admissibility.
The process begins with collecting evidence at the crime scene and depositing it in a secure container. It then travels to a forensics laboratory for analysis and recording. Once there, an inventory will be created of all items collected and stored; additionally, verification that each was properly packaged and assigned a specific storage location.
It is essential to be aware that, should the government fail to uphold the chain of custody during trial, they may be able to suppress some evidence presented at trial. This could play an integral role in whether or not a defendant is found guilty.
Digital evidence requires even greater care in maintaining its chain of custody than physical evidence, since it can be more vulnerable to damage and alteration.
Any break in the chain indicates that the digital evidence is untrustworthy and cannot be presented in court. There’s no way for juries to verify that it was not altered or replaced in any way.
That is why forensics labs must carefully preserve every electronic device seized during an investigation. Doing this prevents any issues with evidence authenticity and allows them to create an inventory which will assist prosecutors in court.
At a criminal or civil legal trial, a forensics expert will work to establish the chain of custody for all digital evidence collected during the investigation. They will inspect each item of digital evidence to detect any flaws or problems which could affect its accuracy; this information will then be documented in an official statement that includes tools, sources of data, methods used to extract information, and any issues identified – all which will then be included in the chain of custody report.
Security Measures
Video surveillance footage can help prove a crime, but it’s essential to understand the rules of evidence before using any footage as evidence. For video to be admissible, it must be relevant, authentic and not altered in any way.
Furthermore, it must be legal and obtained from a reliable source. The prosecution may hire an expert to test the video file to guarantee its validity; they’ll check for corruption, whether anyone in the video was present and if no modifications have been made.
The authenticity of videos is critical since they will be used in court and must be kept secure at all times. Without security measures in place, videos could be altered, reuploaded with different files, or exposed to malicious insiders.
If you want to ensure the security of video evidence, installing a security system that is capable of keeping it unmodifiable is key. This requires encryption at rest and transit to prevent tampering with the file; furthermore, advanced sharing controls like password protection and link expiry should also be in place so the video evidence remains safe until trial.
Another method for protecting video is using a closed operating system (OS). This prevents users from writing any information to the device, especially if it has third-party applications that could potentially attack the system.
Additionally, it’s essential that the video system has a firewall and antivirus software in order to prevent malware download. These tools can shield the video system against attacks from malicious insiders, hackers and bots capable of spreading malicious software.
It’s essential to have a security system that can be monitored so any changes in configuration can be detected and recorded. This is especially true for NVR systems with network shares or remote access capabilities.
In addition to these security measures, it’s also essential that the video footage be transcribed. Doing this helps reduce ambiguity and guarantees everyone in the courtroom can hear what is said.
