Recorded interview transcript
LEAD INSPECTOR: State your full name for the record.
DEPUTY COMMANDER MARK “FROST” FOSTER: Deputy Commander Mark “Frost” Foster
LEAD INSPECTOR: Do you understand the status of this interview and the limits placed on distribution?
DEPUTY COMMANDER MARK “FROST” FOSTER: Yes. Record that I have asked for the original media and audit trail to be preserved.
LEAD INSPECTOR: Have you been offered the representation, legal advice or staff support applicable to this procedure?
DEPUTY COMMANDER MARK “FROST” FOSTER: Yes. I am proceeding under the conditions already stated.
DOCUMENTARY EXHIBIT D-01 Retained extract: MCA - Confrontation with Bureaucracy – Government Red Tape The sterile walls of the Maritime & Coastguard Agency HQ seemed to close in around Natalie Brooks as she walked toward the office of Deputy Commander Mark ‘Frost’ Foster. Associated persons: Natalie Brooks Relevant systems or locations: MCA
LEAD INSPECTOR: Do you accept that this extract accurately records an event in which you were involved?
DEPUTY COMMANDER MARK “FROST” FOSTER: The timing is supportable. Attribution is not. My answer is limited to what I personally saw, heard or ordered.
LEAD INSPECTOR: What did you understand at that moment, before later analysis supplied a larger explanation?
DEPUTY COMMANDER MARK “FROST” FOSTER: I preserved the raw state before testing the explanation. Anything else would have changed the evidence. If the original is no longer available, that absence should remain part of your finding.
DOCUMENTARY EXHIBIT D-02 Retained extract: Foster sat behind his polished oak desk, flipping through a printed maritime report with the kind of detached interest that made Brooks’ blood boil. Associated persons: Natalie Brooks Relevant systems or locations: AIS, MCA
LEAD INSPECTOR: Do you accept that this extract accurately records an event in which you were involved?
DEPUTY COMMANDER MARK “FROST” FOSTER: The timing is supportable. Attribution is not. I will not improve my memory to make the chronology easier.
LEAD INSPECTOR: Who else was physically present and capable of confirming your account without relying on the same electronic record?
DEPUTY COMMANDER MARK “FROST” FOSTER: I preserved the raw state before testing the explanation. Anything else would have changed the evidence. Check AIS against the unprocessed record before you accept the later label.
LEAD INSPECTOR: Are you saying the official record is wrong?
DEPUTY COMMANDER MARK “FROST” FOSTER: I am saying the record should remain evidence, not become an alibi for the system that produced it.
DOCUMENTARY EXHIBIT D-03 Retained extract: That’s not a glitch, Foster. Associated persons: Natalie Brooks Relevant systems or locations: AIS, radar
LEAD INSPECTOR: Do you accept that this extract accurately records an event in which you were involved?
DEPUTY COMMANDER MARK “FROST” FOSTER: The values agree with one another. Agreement is not proof that they describe the real world. Check AIS against the unprocessed record before you accept the later label.
LEAD INSPECTOR: Why was the matter not escalated through the ordinary reporting route?
DEPUTY COMMANDER MARK “FROST” FOSTER: I preserved the raw state before testing the explanation. Anything else would have changed the evidence. My answer is limited to what I personally saw, heard or ordered.
DOCUMENTARY EXHIBIT D-04 Retained extract: "The system flagged it, Foster. Associated persons: Natalie Brooks Relevant systems or locations: Home Office, Southampton
LEAD INSPECTOR: Do you accept that this extract accurately records an event in which you were involved?
DEPUTY COMMANDER MARK “FROST” FOSTER: The timing is supportable. Attribution is not. Check Home Office against the unprocessed record before you accept the later label.
LEAD INSPECTOR: What part of the retained record is incomplete or misleading?
DEPUTY COMMANDER MARK “FROST” FOSTER: That is what the system reported. It is not necessarily what the equipment physically did. Check Home Office against the unprocessed record before you accept the later label.
LEAD INSPECTOR: Are you saying the official record is wrong?
DEPUTY COMMANDER MARK “FROST” FOSTER: I am saying two honest records can disagree when they were generated from the same compromised source.
DOCUMENTARY EXHIBIT D-05 Retained extract: Someone’s testing remote hijacking of vessels." Foster exhaled sharply, pushing himself to his feet. Associated persons: Natalie Brooks Relevant systems or locations: Home Office, Southampton
LEAD INSPECTOR: Do you accept that this extract accurately records an event in which you were involved?
DEPUTY COMMANDER MARK “FROST” FOSTER: I preserved the raw state before testing the explanation. Anything else would have changed the evidence. Check Home Office against the unprocessed record before you accept the later label.
LEAD INSPECTOR: Which physical record should be examined before this account is treated as settled?
DEPUTY COMMANDER MARK “FROST” FOSTER: That is what the system reported. It is not necessarily what the equipment physically did. If the original is no longer available, that absence should remain part of your finding.
DOCUMENTARY EXHIBIT D-06 Retained extract: Foster’s expression flickered, but he masked it quickly. Associated persons: Natalie Brooks, Elaine Morris Relevant systems or locations: AIS, MCA, Home Office, evidence
LEAD INSPECTOR: Do you accept that this extract accurately records an event in which you were involved?
DEPUTY COMMANDER MARK “FROST” FOSTER: The values agree with one another. Agreement is not proof that they describe the real world. If the original is no longer available, that absence should remain part of your finding.
LEAD INSPECTOR: Did anyone instruct you to describe the incident differently afterwards?
DEPUTY COMMANDER MARK “FROST” FOSTER: The values agree with one another. Agreement is not proof that they describe the real world. I will not improve my memory to make the chronology easier.
LEAD INSPECTOR: Are you saying the official record is wrong?
DEPUTY COMMANDER MARK “FROST” FOSTER: I am saying the record should remain evidence, not become an alibi for the system that produced it.
DOCUMENTARY EXHIBIT D-07 Retained extract: "Foster’s not going to—" "I’m not going to Foster," Brooks cut in. Associated persons: Natalie Brooks Relevant systems or locations: AIS, Al Bahr Logistics, Barakah Dawn, MI5
LEAD INSPECTOR: Do you accept that this extract accurately records an event in which you were involved?
DEPUTY COMMANDER MARK “FROST” FOSTER: That is what the system reported. It is not necessarily what the equipment physically did. The missing interval matters more than the wording placed around it afterwards.
LEAD INSPECTOR: What did you understand at that moment, before later analysis supplied a larger explanation?
DEPUTY COMMANDER MARK “FROST” FOSTER: The timing is supportable. Attribution is not. My answer is limited to what I personally saw, heard or ordered.

LEAD INSPECTOR: Who else was physically present and capable of confirming your account without relying on the same electronic record?
DEPUTY COMMANDER MARK “FROST” FOSTER: The timing is supportable. Attribution is not. The missing interval matters more than the wording placed around it afterwards.
LEAD INSPECTOR: Are you saying the official record is wrong?
DEPUTY COMMANDER MARK “FROST” FOSTER: I am saying you should preserve the contradiction instead of choosing the tidier version.
LEAD INSPECTOR: Is there any material fact you have withheld because you consider this recording or its distribution unsafe?
DEPUTY COMMANDER MARK “FROST” FOSTER: Yes. The existence of that fact is the most I will place in this copy.
LEAD INSPECTOR: What is the single next action this investigation should take?
DEPUTY COMMANDER MARK “FROST” FOSTER: Return to the original physical record and identify every hand that altered its custody.
LEAD INSPECTOR: Do you wish to add or correct anything before the recording is suspended?
DEPUTY COMMANDER MARK “FROST” FOSTER: Yes. Do not improve the certainty of my answers in the written summary.
[Recording suspended. Source media sealed. Any resumed session requires a new opening declaration and exhibit schedule.]
