^^I tend to have a similarly dismal view, but I note the following:
1. As long as we have (i) a constitution and (ii) governments that purport to respect the rule of law, there's always the chance that the system can correct itself (I'll admit that I don't see this as a great likelihood); and
2. Given that all powerful interests seek to protect their power to some extent, the fact that Canadian public officials don't strictly adhere to the rule of law is not a shocking revelation. There are degrees of good and bad governance, and it is more meaningful to evaluate Canadian (or Ontario, or Toronto, etc.) society relative to others. In this respect, we're "not as bad" as many places.
None of the foregoing means that we should accept excuses for anything less than optimal governance, of course, but we should be careful in thinking just because some cops get away with crimes up to and including murder, we have to accept that "there is no justice in life". In fact, I would argue that there are large doses of justice in life, and we get angry about the injustice because it is somewhat anomalous.
Anyway, I'll stop now because it feels weird to be talking someone down from abandoning hope in our society. Perhaps I'm just playing mealy-mouthed devil's advocate, because there are days when I would have written exactly what you just wrote.
