What I find most interesting about this is that it's not as though it's a secret. You're the chief of Delta. I used to work in British Columbia, so I'm very familiar with that jurisdiction. This is all very well known. It might not be well reported or publicly discussed, but it's something that I think most people in all facets of the port system or the justice system know about.
I think I know the answer to this, but is there any requirement to have a security clearance? For instance, if you work in a lot of roles, a clearance is required. You couldn't be a correctional officer, for instance, or work for CBSA if you had ties to the outlaw gangs that you were just describing. I'm mindful that they're government.
This isn't government, but access is the key. We often mandate requirements for people who have access to infrastructure, wherein criminality can flourish literally right under our noses. Do you know of any requirements for people, despite having such access, not to be involved in overt criminal behaviour?
