You said the discussion would "lead to a discussion of US drug policy and how the US keeps the cartels in business", which is sort of like saying Chicago in the 1920s was a dangerous place but that we might be able to mention the Mob and prohibition further down the line.
My contention was that the border is not a problem-free zone. And it isn't. And in so doing, I wanted to make it clear I recognized the role of the US in that.
Sweeping changes in US drug policy, on a level to change the demand of meth and heroin in the country, isn't happening. And there isn't a clear solution on that front to eliminate the cartel violence. So while it's totally reasonable to blame the American population for creating the space for the cartel to operate and thereby destroy border cities, there isn't any magic pill to solve the situation from a policy perspective.
