The percentage conviction rate in England & Wales is often higher than in Scotland but this is where, as with drug deaths, you need your sceptical wits about you. What percentage of those arrested actually make it to court?

In 2023/2024, the latest available, 14.4% of those 2 522 arrested (362) were tried and 61% (221) convicted. https://www.gov.scot/publications/criminal-proceedings-in-scotland-2023-24/pages/key-points/

In England and Wales, the equivalent figures for the same year were: 4% of 67 900 arrested, 2283 tried and 53.4% even of than much smaller percentage tried, 2283 convicted.

So, in that year, per head, pro rate, Scotland has barely a third of the reported cases (2 522 to 67 900) but still tries more than three times the percentage (14.4% to 4%) and then even convicts more! (61% to 53.4%).
