Original post by Baron of SealandI live in Mexico (which would make me around less than half as rich as one in Hong Kong). I didn't realize the time anyone spends at Oxford qualifies anyone to talk about Latin America. I guess that's why you feel like you get to make comments and judgements like those, even though your knowledge of Latin America seems to be on par with some Hollywood directors.
And I live in the second-most dangerous state, in the city which has so far half of all its homicides this year. And I have gone to many so-called no man's land (and alone) in 22 states + CDMX. I have spent the holiday with a (poor) family in Michoacan,I have hitchhiked in San Luis Potosí, I have gone into the mountains in Chihuahua which has the highest homicide rate in the country, I have taken public transport, including combis/colectivos and microbuses. I have personally been a victim of crimes (including a violent one - although that's in Brazil, the other country you named), and I even have had the police called on me. And yes, I have experienced multiple police extortion efforts too.
So yes, I do think I'm more capable of judging the real world than you, whether we even go into the fact that I have visited every single country on mainland Latin America, while you seem to just be holding on to the few years you spent at Oxon.
I'm very well aware of what the cartels have done. But you claimed that these countries are effectiveness lawless in a state of civil war, and that the havoc the cartels cause is comparable to that of ISIS. Well, no. The fact that there isn't a refugee crisis in Mexico or Brazil already suggests that the situation isn't near as bad as you think.
In your mind, all of Brazil is the dangerous zones in Rio de Janeiro, and all of Mexico is basically what you can see from Weeds or Queen of the South. Sorry to break this to you, but being an Oxonian lawyer doesn't mean you have all the knowledge in the world.

And since you seem to be more keen on personal attacks rather than defending your viewpoints, let me tell you something in advance: in this particular case, we certainly don't know the fact, and we most definitely can disagree with the method. But your point seems to be that citizens taking matters into their own hands was already barbaric and that anyone sane person should see it that way. I will have you know apart from cartel violence among themselves, things like this are rare. What's common would be people caught in the act and get beaten up (I'd say that's good enough evidence), or people who were literally videoed multiple times robbing shops, people, combis, and homes, and they get beaten up (I'd say that's good enough evidence too). There are good police officers, but most of the time if you go to the police with a video, even in somewhere like Hong Kong the police would not be too enthusiastically solving your case (they'd only be more proactive if someone is caught in the act), and in Mexico it could mean a long waiting time, multiple bribes, and for those criminals to continue offending.
It's all well and good that you say it's better to improve the police force, but that's clearly not something individuals have the power to do. You don't seem to appreciate the fact that your suggestion based on ignorance is basically just to do nothing and let criminals get away with whatever.
Don't forget even in the UK, rape cases are very difficult to prove, and many alleged rapists walk free. There's a reason why mob lynching doesn't really happen with most other crimes (I'm not even aware of revenges on murders). The people feel powerless and are empowering themselves, and you are someone living in the first world judging people you know nothing about from your computer screen.
