Yes. This debate has continued for many years. The policy was instituted by Richard Brunstrom when he was ACPO Head of Road Policing. I have campaigned against the stupidity of extended ‘Crime Scene’ forensic closures on the grounds that by diverting large volumes of traffic onto unsuitable roads, more death and destruction can occur. Similarly, drivers and passengers held up for six hours in the same place can suffer severe discomfort and can even die. In their favour the police only close a road when they absolutely have to in order to establish the true cause of a death and determine blame for the insurers.
