Police services have been reported to have applied for permission to use surveillance drones (automated planes with CCTV) for police work in the UK. These were originally designedfor military intelligence. These should not be used for ordinary policing. Such equipment should be highly regulated and their use only allowed on a time limited basis in exceptional circumstances- not for everyday crime and violence.
Why is this idea important?
In the UK we tend to be complacent about our rights but they have only been strong to date because protected and defended. Surveillance and coercive powers of the state need to be tighly controlled to ensure that agencies do not become complacent about our rights.
These planes can't be seen (they fly very high) and are intrusive. Though there may be exceptional circumstances when they might be used- they must be the exception.
