> I would say your entire argument is completely debunked.

With all due respect, I did not have any argument.

I was reading your conversation, I had difficulty seeing a contradiction, so I asked a question.

You've introduced one more statement instead, "mass arrests with long-term sentences have drastically reduced crime rate in El Salvador". I see your point but this doesn't really help me with my original question. How do we know that it's the sentence terms is a significant factor (out of the combination), and not the mass arrests or something else? We don't have a control group, do we?
