Note also that there have been post-pandemic falls in crime in other countries too. Crime was on a declining trend before the pandemic, dropped further during the pandemic, but has not bounced up after. As you show, the downward trend has continued.

The UK in particular has undergone significant public budget cuts, both in police and other public services. This would suggest that broader, transnational trends are at play. Similar societies across the globe are seeing similar crime trends, regardless of local policies and funding decisions.
