The 37 Scientific Evidence of Digital Evidence Tampering on CCTV Footage at Olivier Café: The Jessica Kumala Wongso Case (2016), Carried Out by Muhammad Nuh Al-Azhar and Christopher Hariman Rianto, Who were Under the Leadership of the General Crime Director of the Jakarta Metropolitan Police, Krishna Murti, and the Chief of the Jakarta Metropolitan Police, Tito Karnavian.  EVIDENCE 14: CCTV 2 FOOTAGE DELIBERATELY CONVERTED FROM COLOR TO GRAYSCALE CCTV 2 footage was divided into two parts: the first part from 13:55 WIB to 16:02 local time (as per the Examination Report of Muhammad Nuh Al-Azhar) and the second part from 16:02 to 18:06 local time (as per the Examination Report of Christopher Hariman Rianto). Metadata analysis of both parts of CCTV 2 footage shows that the video has three color channels (YUV color space), indicating that CCTV 2 footage is a color video. However, when displayed in court by Christopher Hariman Rianto, Muhammad Nuh Al-Azhar, and the prosecutor, the video turned into grayscale (only one channel). This confirms that CCTV 2 footage was deliberately converted from YUV color space to grayscale.  The forensic impact of this manipulation is very significant. The color information captured by camera 2 is crucial to provide details about the volume and color of the remaining coffee glass carried by Devi Siagian from the pantry to the cocktail bar. The color of the coffee glass should indicate whether there was any color change alleged to be caused by contamination or a harmful substance such as cyanide. This vital information was destroyed by Muhammad Nuh Al-Azhar and Christopher Hariman Rianto.  Furthermore, the color information of Mirna Salihin's face and arms when she was taken in a wheelchair from table 54 out of the Olivier café around 17:28 local time should have been carefully analyzed. Skin color can show physical signs such as paleness or other color changes that might indicate certain medical conditions due to poisoning. This vital information was also deliberately destroyed by Muhammad Nuh Al-Azhar and Christopher Hariman Rianto.  This video manipulation removes crucial visual evidence. The removal of color information by digital forensic experts, who should maintain the integrity of every bit of information in this video, demonstrates a serious breach of professional ethics.

00:00Australian resident Jessica Wongso has been charged with the murder of Minis Alihin.

00:10Police allege she poisoned her friend by adding cyanide to her coffee.

00:14Jessica is like a devil.

00:17Deep inside is something like evil.

00:20It is said that the trial of the century is true.

00:29CCTV-2 footage deliberately converted from color to grayscale.

00:34CCTV-2 footage was divided into two parts, the first part from 1355 WESTERN INDONESIAN

00:40TIME to 1602 LOCAL TIME, as per the examination report of Mohamedna Al-Azhar, and the second

00:46part from 1602 to 1806 LOCAL TIME, as per the examination report of Christopher Harriman

00:52Rianto.

00:54Metadata analysis of both parts of CCTV-2 footage shows that the video has three color

00:59channels, YUV color space, indicating that CCTV-2 footage is a color video.

01:04However, when displayed in court by Christopher Harriman Rianto, Mohamedna Al-Azhar, and the

01:10prosecutor, the video turned into grayscale, only one channel.

01:15This confirms that CCTV-2 footage was deliberately converted from YUV color space to grayscale.

01:22The forensic impact of this manipulation is very significant.

01:26The color information captured by camera 2 is crucial to provide details about the volume

01:31and color of the remaining coffee glass carried by Devi Siajian from the pantry to the cocktail

01:36bar.

01:37The color of the coffee glass should indicate whether there was any color change alleged

01:40to be caused by contamination or a harmful substance such as cyanide.

01:46This vital information was destroyed by Mohamedna Al-Azhar and Christopher Harriman Rianto.

01:52Furthermore, the color information of Myrna Salihan's face and arms when she was taken

01:56in a wheelchair from Table 54 out of the Olivier Café around 1728 local time should have been

02:02carefully analyzed.

02:04Skin color can show physical signs such as paleness or other color changes that might

02:09indicate certain medical conditions due to poisoning.

02:12This vital information was also deliberately destroyed by Mohamedna Al-Azhar and Christopher

02:17Harriman Rianto.

02:19This video manipulation removes crucial visual evidence.

02:23The removal of color information by digital forensic experts, who should maintain the

02:27integrity of every bit of information in this video, demonstrates a serious breach of professional

02:33ethics.

02:34This manipulation not only obscures the truth of the events that occurred but also undermines

02:39trust in the forensic analysis results presented in court.

02:44Manipulating the video from color to grayscale also casts a shadow over the credibility of

02:48the forensic experts involved.

02:50Forensic experts are expected to uphold the highest standards of integrity and ensure

02:54that the evidence they present is as accurate and unaltered as possible.

02:59The deliberate conversion of the video from its original color format to grayscale is

03:03a serious breach of these professional ethics.

03:07It suggests an intention to obscure or manipulate the evidence, which can severely damage trust

03:12in the forensic findings and the judicial process as a whole.

03:16Moreover, the loss of color information limits the ability of all parties involved in the

03:21trial to see the complete picture.

03:23Judges and lawyers rely on video evidence to provide a clear and comprehensive understanding

03:28of the events in question.

03:30Color can influence perception and interpretation, making it a critical element of visual evidence.

03:37The absence of color can lead to misinterpretations or a lack of clarity about what actually transpired,

03:42thus potentially affecting the outcome of the trial and the delivery of justice.

03:47Finally, the manipulation of the video has broader implications for the judicial system.

03:53It highlights the importance of ensuring the integrity of digital evidence and the role

03:57of forensic experts in preserving this integrity.

04:01Any manipulation or alteration of evidence can lead to miscarriages of justice, where

04:05the guilty may go free, and the innocent may be wrongly convicted.

04:10This case underscores the need for stringent protocols and oversight in the handling and

04:14presentation of digital evidence to maintain public confidence in the judicial process

04:18and ensure that justice is served based on accurate and reliable evidence.

04:24Understanding the motives of Muhammad Nuh Al-Azza and Christopher Harriman Rianto in

04:27converting the CCTV-2 footage from color to grayscale requires a thorough examination

04:32of the context and potential benefits they might have sought to achieve in their efforts

04:36to criminalize Jessica Wongso.

04:39One possible motive could be to obscure specific details that would have been detrimental to

04:43their case against Wongso.

04:46By eliminating the color information, they might have intended to hide critical details

04:50in the coffee glass carried by Devi Siajian.

04:54The color information in the coffee could have provided crucial evidence refuting allegations

04:59of poisoning, and removing this evidence would weaken the defense's argument, thus strengthening

05:04the prosecution's case against Wongso.

05:07Another potential motive could be to create ambiguity and cast doubt on the reliability

05:12of the evidence.

05:14In a legal setting, the ability to introduce uncertainty can be a powerful strategy.

05:20By presenting a grayscale video, they might have aimed to make it harder for the defense

05:24to draw definitive conclusions about the events depicted.

05:28This ambiguity could work in favor of the prosecution by making it challenging for the

05:32defense to prove that poisoning did not occur.

05:35Essentially, by manipulating the video, they could create reasonable doubt in the minds

05:40of the judges about Wongso's innocence.

05:42Additionally, Mohamedna Al-Azza and Christopher Harriman-Rianto might have had personal or

05:47professional incentives to manipulate the evidence.

05:51They could have been acting under pressure from their superiors or from a public expectation

05:56to secure a conviction against Wongso.

05:59In high-profile legal battles, the pressure to win can sometimes lead individuals to engage

06:04in unethical behavior.

06:06If their careers or reputations were tied to the success of the case, they might have

06:10felt compelled to alter the evidence to increase their chances of achieving a conviction.

06:15Moreover, the manipulation of the video could have been part of a broader strategy to control

06:19the narrative and the perception of the forensic process.

06:23By presenting manipulated evidence, they might have intended to bolster the credibility of

06:28their case while discrediting the defense's argument.

06:32If they could ensure that the prosecution's evidence appeared consistent and reliable,

06:36it would strengthen their position and potentially lead to a conviction.

06:40This strategy hinges on controlling the flow of information and maintaining a favorable

06:45perception of the prosecution's case.

06:48Lastly, their actions might reflect a broader pattern of misconduct or systemic issues within

06:53the legal and forensic systems they operate in.

06:56If manipulating evidence is a common practice in their professional environment, they might

07:01have seen their actions as a standard, albeit unethical, part of prosecutorial conduct.

07:07This systemic issue would suggest that their motives are not just individual, but also

07:11a reflection of a corrupt system where such behavior is normalized or even encouraged.

07:16Addressing this would require not only holding the individuals accountable, but also implementing

07:21reforms to ensure the integrity of the legal and forensic processes.
