No, it's premised on the question of whether the proposed alternative is better, which it isn't. There are problems with the criminal justice system (as a lawyer, I've worked in it); debate over how to change it and what the impact of changes have been is a constant process, as well, and the general direction has been positive.
I don't know how you solve systemic racism within the structures of society that continue to reproduce it though and I'm not even going to pretend to have an answer.
But let's say one answer is to have more Indigenous judges and crown lawyers in Canada to be able to better fight against the biases that exist in the system, then the question becomes how do you get more Indigenous peoples into law school? And then you begin to tease apart questions of whether Indigenous peoples should be subjected to colonialist power structures in order to attempt to make it fairer, starting with the fact that they would be servants of the crown. But even before you have that conversation, you have to think about how some of these people are supposed to worry about getting into college and law school and the ethical issues that come with serving the crown when they don't even have safe drinking water.
I know it's not as important as the law, but as someone who is adjacent to memory institution work and the call for the decolonization of libraries and archives, the same issues apply. There are people working in this space, but the fact that you need at least 6 years of education to work in a library or an archive - and then in the case of working for LAC, you also need to be bilingual as well - creates the conditions where you essentially exclude the people who you need to help dismantle the power structures that we all understand are problematic.
I hope people are able to put in the work to tease out and solve some of these issues. I'm at a point where I'm happy to let it go because the emotional labour is damaging to my mental health and I'm okay with contributing by living my own life as best as I can without harming others.
I have not seen anyone suggest that gun violence is not a problem. You're confusing people not thinking that your proposed solution is either desirable or practical or would have the effect you seem to want with people not thinking it's a problem in the first place.
Both the Liberals and the Conservatives have made political calculations about how to tackle gun control to maximize the votes that they can get. Which is why our action is essentially inaction - in the current Liberal case, unless they've changed their policy, it's to allow jurisdictions to set their own laws. I don't even care if that's a right or wrong choice anymore. I just recognize that it's the most politically convenient.
