No, I'm not. I just don't see the point if it didn't work before.Again, you're missing that this is only a component in larger efforts to reduce crime.
But lets say it does NOTHING to reduce crime, it is still a net positive because the content they are banning literally glorifies drug use and violence. That alone is worth it.
They are using an argument for morality to shift blame to creatives and not the root cause of their problems.
