Hack the Police 4

Join us on the 14th and 15th September, 2019 for a weekend of exploration and innovation. Learn about policing, make new friends, and build new tools to help investigate crime and uncover the perpetrators...

A hackathon is a creative event: You won't be hacking into things, you'll be hacking new prototypes together... đź‘Ť

This year our theme is investigation - from crime scene to case file. You'll get a chance to work alongside serving police officers, detectives and scene of crime investigators to create something new.


We'll be in our London Blackfriars venue again, with thanks to Computacenter, our hosts for this year and last.

Police officers

Policing professional tickets are available! Once you have your ticket, please visit our discord channel #hack-the-police-4 to interact with our participants.

If you'd like to share an idea for an innovation in policing, you can add it to the ideas database. We'll make sure you're fully credited (if you wish to be), and put you in contact with any teams that choose to work on the idea or anything similar (if you agree to that).

Police Rewired

Police Rewired are a group for volunteer professionals, building tools in public safety and policing. We fight crime with code.

Our community is open to developers, designers, data scientists, students, academics, criminologists, crime scientists, serving police officers, and creative problem solvers!

We are all volunteers, our projects are open source, and we build in the open.

Q: What size teams can participate? A: You may form a team of any size or hack as an individual. Teams of size 1 to 4 people are eligible for a prize.

Q: Can I apply on behalf of a friend? A: Each person coming must apply for their own ticket. At the hack, you can work in teams of 1 to 4 with whoever you like to be eligible for a prize in one of the categories.

Q: Can we stay over? A: If you are over 18 years old, you can stay over at our London Blackfriars venue. Bring a sleeping bag and pillow (if you're not planning to hack all night!)

Q: What should I bring? A: You'll need a laptop and a charger. If you're staying over, also bring a wash bag, change of clothes, sleeping bag, pillow. There's a shower at our London Blackfriars venue so bring a towel, too.

Q: Who supports Hack the Police? A: Hack the Police is the Police Rewired annual hackathon. We run it in partnership with our sponsors, and with the support police forces and policing bodies. Find out more about our partners below...

Q: I have a brilliant idea. Can I share it with teams at the event? A: Yes, you can add it to our ideas database. We'll make sure you're fully credited (if you wish to be), and put you in contact with any teams that choose to work on the idea or anything similar (if you agree to that).

Q: Will there be prizes? A: We love prizes! They will be fun and policing themed.

Q: What are the prize categories? A: TBC! We will announce the prize categories closer to the date of the event.

Q: Do Hack the Police projects have an impact? A: Wow, what a question for an FAQ! We do hear it a lot though. In short, yes - some projects from previous hacks have gone on to feed the development of innovations in production. We'll have representatives from police forces and the College of Policing at Hack the Police 4 who are looking for projects with potential. An example: At Hack the Police 2, teams worked with Dr Fiona Gabbert and the Forensic Psychology Dept at Goldsmiths to prototype the Self-Administered Interview. It's being taken on and developed by a major police force now.

Q: Who owns the rights to my project? A: You do. We'd love for you to build your prototype as an open source project - and we encourage use of open collaborative repository tools such as github. If our sponsors or supporting police organisations are interested in working with you to develop it, we'll be glad to help facilitate contact.

Q: I'm a police officer, can I come? A: Yes! Grab your ticket, and Join the Police Rewired community, or visit our discord channel #hack-the-police-4.

Police officers: After the event opening and ideation, we'll ask you to visit the teams during the day to help them organise their thoughts, try out ideas on you, and develop their project plans into something they can prototype. You can then settle with a team to help them some more if an idea really stands out to you.
