Do you have a source for these stats? Otherwise, that is some serious conjecture, not to mention that disorder is a very broad concept. Given the size of Edmonton, 200-300 people seems remarkably low, as most petty crime goes unreported. Generally, 1-3% of the population commits violent crime, while higher proportions commit petty crime. Our prison system doesn't have the capacity to house that many people long-term, assuming justice reform were to enable longer prison terms. Given that we won't even commit to building more hospital capacity as a society, I doubt there would be much appetite to increase prison capacity that much, along with the associated operating costs.
