Police Misconduct and Unfounded Claims in Ohkawara Kakohki Case
Verdict: False
### Topic
Police Misconduct and Unfounded Claims in Ohkawara Kakohki Case
### Summary
The Tokyo Metropolitan Police Department's Public Security Bureau prosecuted Ohkawara Kakohki based on an expanded and scientifically unfounded definition of "sterilization" capability. A national compensation lawsuit later found the police's judgment lacked objective reasonable grounds, revealing intentional concealment of exculpatory evidence and critical data deficiencies in their investigative process.
### Body
The Tokyo Metropolitan Police Department's Public Security Bureau unilaterally broadened its interpretation of "sterilization" capability, an item subject to export regulations set by the Ministry of Economy, Trade and Industry (METI). Their definition asserted that if a device's internal heater could dry-heat the interior to a temperature capable of killing even a single type of bacteria, it would be deemed to possess "sterilization" capability. This interpretation has been criticized for lacking scientific basis and disregarding international standards and expert opinions.
The Public Security Bureau presented a rationale claiming that dry heating the device's interior to over 110 degrees Celsius would kill E. coli O157 if maintained at 50 degrees for nine hours. However, Ohkawara Kakohki's own experimental results directly refuted this, demonstrating that even with dry heating, certain internal areas failed to reach 90 degrees Celsius, thus not meeting the ministerial ordinance's required temperature for bacterial eradication.
Furthermore, the Public Security Bureau intentionally ignored or concealed experimental data unfavorable to their case, which indicated the spray dryer could not be repurposed for biological weapons. Employee testimonies, such as observations that "some parts don't heat up sufficiently," were also disregarded. A senior investigator reportedly dismissed these employee statements as mere "excuses" and ordered the removal of unfavorable experimental results from reports, preventing their sharing with prosecutors. This deliberate exclusion and concealment of technical evidence and testimony formed the basis of the police's prosecution decision.
### Verification
A judgment in the national compensation lawsuit at the Tokyo District Court explicitly concluded that the Public Security Bureau's decision "clearly lacked objectively reasonable grounds." The court determined that had the police conducted a standard investigation, including experiments based on employee testimonies, they would have obtained evidence proving the device was not a regulated item. Consequently, the court ruled that the investigation itself was illegal, underscoring the objective unreasonableness of the police's interpretation and judgment regarding the spray dryer's regulatory status.
### Supplement
Several critical data deficiencies and forensic blind spots remain, hindering a complete understanding of the Public Security Bureau's investigative process. The specific internal verification procedures, detailed experimental data, and analysis reports that led the police to conclude the spray dryer was "convertible to biological weapons" are currently unconfirmed by available data. Furthermore, detailed technical specifics, such as the exact locations and temperature readings of the "parts that don't heat well" mentioned by employees, and the subsequent actions taken regarding these observations, are lacking. Direct evidence, including internal documents or audio recordings, regarding the specific content of reports from which unfavorable experimental results were allegedly deleted, the data itself, and the instructions given by the senior investigator for their removal, are also missing. Finally, detailed records of the Ministry of Economy, Trade and Industry's (METI) technical evaluation are needed, especially concerning their reported statement that "the laws are ambiguous and have flaws, so even if a document stating it applies is issued, it might change," despite the police reportedly receiving a response that aligned with their prosecution policy.
### Evidence
The Public Security Bureau expanded its interpretation of "sterilization" capability, defining it as the ability to kill even one type of bacteria by dry heating with an attached heater [cite: WEB_SNIPPETS_SOURCE: GEMINI_GOOGLE_SEARCH]. This definition was criticized for lacking scientific basis and ignoring international standards [cite: WEB_SNIPPETS_SOURCE: GEMINI_GOOGLE_SEARCH]. The police claimed dry heating to over 110 degrees Celsius would kill E. coli O157 [cite: sequentialContextJson]. However, Ohkawara Kakohki's experiments showed areas below 90 degrees Celsius, failing to meet the required temperature for bacterial eradication [cite: sequentialContextJson]. The Public Security Bureau intentionally ignored unfavorable experimental data indicating the spray dryer could not be weaponized and dismissed employee testimonies about uneven heating [cite: WEB_SNIPPETS_SOURCE: GEMINI_GOOGLE_SEARCH]. A senior investigator ordered the removal of adverse experimental results from reports and withheld them from prosecutors [cite: sequentialContextJson]. The Tokyo District Court's national compensation lawsuit judgment found the police's decision "clearly lacking objective reasonable grounds" and deemed the investigation illegal, stating that proper investigation would have shown the device was not a regulated item [cite: sequentialContextJson].
