I downvoted it because it was off-topic. When we're talking about the US justice system - which we do fairly regularly - then it's a useful comment. Here it's just a red herring.
And I downvoted you for not understanding that distractions hijack the conversation. A conversation about everything is too unfocused to be a useful conversation about anything. The topic here is Dubai; you're fine with it being hijacked into a conversation about the US justice system. I'm not OK with that. Let us talk about Dubai here; we'll talk about the US justice system plenty of other places.
