Amazon is once again at the centre of a privacy row after a judge in the US asked the firm to hand over audio recordings from an Amazon Echo.

The potential use of smart speakers for law enforcement has also been explored in the UK.

In January this year Lancashire Police investigated whether smart speakers could be used to collect reports from the public and to disseminate information on crime.

The Lancashire police idea was to use AI assistants to allow people to file crime reports and witness statements from their own home, thereby reducing the strain on 999 call centres and on officers.

But on the other side of the pond, the Amazon Echo is once again at the centre of a murder investigation.

The BBC reported that the US judge has also requested that Amazon hand over any additional data, including if the Echo speaker was paired with other devices at the time the women were attacked in January 2017.
