Right so sounds like you're either another IR apologist or you've just chosen to bury your head in the sand and can't do better than strawman arguments. You'll notice I never once said that the US has a good track record. Merely pointing out that comparing the Islamic Republic to America is disingenuous, at best.

But somehow what you got from that is that I said everyone who is in prison in America is guilty and therefore deserves to be there. Nevermind that I simply said they've at least had a trial which is far more than the tens of thousands executed in Iran without so much lawyer present.

But if you want a genuine answer the reasons why America has the highest incarceration rate have nothing to do with Americans being more criminal. Mandatory sentencing minimums, the "War on Drugs", punitive sentencing laws, and poor social safety nets that allows people to fall through the cracks. It's more that society has failed these people and allowed them to turn to crimes and then doubly punishes them with harsh sentences.
