Hmm US policing and UK policing as well as many European policing are very different in my experience
In the UK we have the policing by consent traditions which loosely defines the key principles of UK policing, through the ‘General Instructions’ or the so called Robert Peel’s 9 Principles Policing.
The US policing approach appears to be of a semi military style law and order enforcement approach.
For example the UK Police training may focus on the use of space and time to deescalate, where as in the US there is a reliance of escalated use of force. (source J Cobbina, associate professor in criminal justice, Michigan State University)
Now I agree the PCC (Police and Crime Commissioners) are contentious as they introduce regionalised main stream political thinking into where to set priorities including resources to focus on the more distinct policing needs of an area at the same time supposedly bringing local accountability… but to my mind that is removed from the discipline of policing itself.
Further the NPCC (National Police Chief’s Council) provides a degree of uniformity in approach, coordination and national reform and improvement across all UK police forces.
