There’s plenty of intriguing and heartening news in the latest national crime report. This week, Statistics Canada released its annual compendium of data, based on information provided to hundreds of police departments across the country. Many media reports seized on the simple, big-picture stats: the overall crime rate reached its lowest level since the early 1970s. It would be wrong to key on this as the most important finding. It may be the least useful statistic and likely tells us absolutely nothing about whether the true level of crime has declined in the past 40 years and whether communities are any safer now than they were in the 70s.
