Problem

Domain: Law-enforcement digital evidence management

An Garda Síochána needed to modernize frontline policing and digital evidence workflows while operating under legislation that limited large-scale AI analysis.

Constraints:

Architecture

An Garda Siochana is building the digital evidence foundation first: mobile devices, body cameras, public upload, and evidence management create the data layer, while AI recognition and search remain gated by legislation and human accountability.

Data flow

Evidence flows from mobile devices, body cameras, public uploads, CCTV, crime scenes, and 999 recordings into a digital evidence system before any AI-assisted search or analysis can be applied.

“our digital evidence system will be managing all of this data. So, whether it's CCTV, crime scene analysis, public upload, um 999 phone recordings”transcript, stated

Why this architecture

The architecture keeps humans first because enforcement decisions and AI evidence use are constrained by due process and pending legislation.

“All of our all of our systems are human first. They we we use human we use obviously an awful lot of technology to get to a point, but then a human will make the decision.”transcript, stated
“At the moment, we're not allowed to do that. We need the AI legislation. The next one, looking to search for a car or a bicycle.”transcript, stated

Models used: planned object recognition AI · planned transcription tools · planned live translation tools

Scale

Alternatives considered (roads not taken)

Deploying broad AI evidence search as soon as the technology works

Rejected because: The team cannot use those capabilities until AI legislation allows them, so the system emphasizes evidence infrastructure and human decisions first.

“At the moment, we're not allowed to do that. We need the AI legislation. The next one, looking to search for a car or a bicycle.”transcript, stated

Fully automatic enforcement decisions

Rejected because: The source emphasizes multiple human checks before enforcement outputs such as speed-van penalties are issued.

“if you see the speed van and you get caught by it, just be happy to know that there's three people will look at that before it comes out in the post. So, it's not an automatic thing.”transcript, stated

Manual frame-by-frame video search as the long-term evidence workflow

Rejected because: The source describes frame-by-frame review as the current pain that future AI search is meant to address once legislation permits.

“there's 99 people we were trying to find after the Dublin riots. And the guards literally had 40,000 hours of video and they went through it frame by frame”transcript, stated

Patterns

human-in-the-loop-gate (safety)

Automation supports evidence and enforcement workflows, but humans remain responsible for decisions before enforcement actions are issued.

“All of our all of our systems are human first. They we we use human we use obviously an awful lot of technology to get to a point, but then a human will make the decision.”transcript, stated

privacy-preserving-processing (safety)

AI-enabled evidence search is gated by legislation and data-protection review before broad processing of public and body-camera footage.

“The challenge is we have another bill which is the digital recording devices bill amendment and unfortunately they put FRT rather than AI in the name of the bill.”transcript, implied

Tradeoffs

How much enforcement decision-making to automate.

Chose human-first review over fully automatic enforcement decisions.

Rationale: The organization uses technology to narrow and prepare work, but keeps accountable humans in the decision path for sensitive policing outcomes.

“if you see the speed van and you get caught by it, just be happy to know that there's three people will look at that before it comes out in the post. So, it's not an automatic thing.”transcript, stated

Gotchas (what bit them)

Useful AI evidence analysis could not be deployed just because the technology existed.

Root cause: Legislation allowed some body-camera processing but not the broader AI/FRT capabilities the team wanted.

Resolution: Proceed with permitted evidence workflows while preparing tenders, systems, and trials for future legislation.

“At the moment, we're not allowed to do that. We need the AI legislation. The next one, looking to search for a car or a bicycle.”transcript, stated

Manual video review does not scale to major incidents.

Root cause: Investigators had thousands of hours of footage but no approved way to compare people, events, or vehicles at scale.

Resolution: Use manual public-identification workflows now and pursue object/event recognition once legally allowed.

“there's 99 people we were trying to find after the Dublin riots. And the guards literally had 40,000 hours of video and they went through it frame by frame”transcript, stated

Digital evidence volume creates chain-of-custody and storage complexity.

Root cause: Evidence spans CCTV, public uploads, calls, interviews, body-worn footage, mobile devices, and seized laptops or phones.

Resolution: Centralize handling in a digital evidence system that can manage originals and working copies.

“our digital evidence system will be managing all of this data. So, whether it's CCTV, crime scene analysis, public upload, um 999 phone recordings”transcript, stated

Evaluation

The talk reports operational examples from mobile policing and manual riot-identification workflows rather than AI model benchmarks.

Metrics: about 16,000 managed mobile devices · 15,000 uninsured vehicles removed from the road · 99 people sought after the Dublin riots

“by the end of 2024, we now have 15,000 plus as of yesterday it's about 16,000 or what is it? 15,825 mobile devices managed by An Garda Síochána.”transcript, stated

Outcomes

Public-sector conference talk; AI capabilities are mostly planned, researched, or legislation-dependent.

“last year we took 15,000 vehicles that were uninsured off the road. We also have an app that manages 999 incidents.”transcript, stated
