It is extremely important that we have adequate and appropriate technology. Of course the battery life of these cameras on the frontline is a key part of that. Police using the system being rolled out in
the west midlands, which is partly funded through the Home Office, are confident that they can use the cameras from when they are automatically triggered through to when the footage can be uploaded back at the station. As has already been pointed out, research strongly suggests that the use of force is reduced by about half if body cameras are worn. Attacks on police officers are also reduced. In the west midlands, harm to police officers has been reduced by about three quarters since body cameras started being routinely used, and complaints against police officers have fallen by more than 90% when evidence from a body camera is used.
There has been great progress in the area of mental health, but there is still much more that needs to be done. We need a greater focus on mental wellness, prevention, early intervention and ensuring that primary care is in a position to support and treat our patients at an early stage. There will always be occasions when restraint is appropriate and even a small number of circumstances in which the use of force is necessary. That use of force must be properly regulated, registered, controlled and used as a last resort—when no other adequate course of action is available.
