Lotoc Defends NBI Findings as Defense Raises Errors in Impeachment Records
Jeremy Lotoc said clerical discrepancies did not alter the underlying video or the bureau’s findings, while the defense argued that document integrity matters in a trial carrying constitutional consequences.

A second witness takes the stand
National Bureau of Investigation regional director Jeremy Lotoc testified as the prosecution’s second witness on the alleged-threat article. A former head of the NBI Cybercrime Division, Lotoc described the stages used to handle the Duterte recording: identifying and preserving digital material, collecting and hashing files, examining their contents and evaluating possible legal action. His testimony was intended to reinforce the foundation laid by senior agent John Mark Calilung.
The defense focuses on the paperwork
The defense drew attention to typographical errors, inconsistent docket details and other discrepancies in documents connected to the investigation. This was not a trivial line of questioning. In any proceeding involving digital evidence, the paperwork surrounding collection, transmission and examination helps establish that the material remained identifiable and reliable. The defense argued that errors could weaken confidence in the process and in the conclusions prosecutors wanted the court to draw.
Lotoc’s answer
Lotoc acknowledged clerical imperfections but maintained that they did not alter the recording, the files examined or the NBI’s essential findings. The prosecution later described his testimony as corroboration of Calilung’s account. That was the prosecution’s assessment, not a ruling by the impeachment court. The senator-judges still had to determine how much weight to give the testimony and whether the identified discrepancies were harmless mistakes or signs of a deeper reliability problem.
The wider meaning of the exchange
The hearing exposed two different ways of understanding evidence. Prosecutors emphasized the substance: a public recording, a documented investigation and witnesses who said the material was authentic. The defense emphasized the safeguards: exact records, consistent identifiers and a process that must be strong enough for a constitutional trial. Both questions are legitimate. Evidence can be highly important and still require strict scrutiny.
Why It Matters to Us, Filipinos
Public accountability does not become stronger when procedural weaknesses are ignored. It becomes stronger when important evidence can withstand detailed inspection. The defense had the right to challenge the NBI’s records, while prosecutors had the responsibility to explain why the mistakes did or did not affect reliability. For Filipinos, the real public interest is not in giving either side an easy victory. It is in a verdict that can be understood and defended after the political noise fades.
What happens next
After Lotoc’s testimony, prosecutors narrowed their Article IV witness list and prepared to call NBI Director Melvin Matibag. The court would then hear the bureau leadership’s assessment and the defense’s objections to the opinions and information he relied upon.
