I deal with numbers and I see those (England, Wales, Australia, USofA) as "ballpark" close to each other .. relative to 170+ other countries about the globe.
The UK and Australia have similiar policing roles and behaviours, quite different to the US - more uniform within the countries, significantly less use of guns and force, etc.
Ballpark, but under Australia's 264 per 100,000, more than England and Wales at 227 per 100,000 and less than Scotland at 318 per 100,000.
