A button inside the police car triggers a lid to pop up releasing a GPS bullet that shoots out and sticks to the suspects car. The system, dubbed Starchase, is already in use in four US states – Iowa, Florida, Arizona and Colorado – and the firm behind it is now keen to get the system into the UK. It costs $5,000 (£3,108) to install and each bullet costs $500 (£312). http://www.bbc.co.uk/news/technology-24731080
A button inside a police car triggers a lid to pop up releasing a bullet that shoots out and sticks to the car in front.

Once the bullet is connected to a car, the police can stop the chase. They can track and pinpoint a suspect’s vehicle location and speed in near real time.
Dave Allen is a senior lecturer at Leeds University and recently co-authored a report into the future of technology for the UK police. “This sounds like interesting technology and there is a clear operational use for it. I think the costs will fall rapidly and we will see them being used routinely in the not so distant future,” But, he added, there needs to be pause for thought to make sure technology is not just being used for technology’s sake.
“There are other ways to track vehicles and this could raise some civil liberties issues,” he said.
