> When societies manage to "stomp out" crime they're no less brutal than when they attempt to stop a pandemic.
I don't think this is necessarily true. Because when trying to stamp out a pandemic, everybody was negatively affected. When trying to stamp out crime, it's overwhelmingly suspected criminals that are affected. Not long ago El-Salvador had literally the highest homicide rate in the world and was just a domestic war-zone. It's now rated as the 8th safest country in the world [1].
What did they do? Dramatically bump up the penalties for gang membership, round up gang members, and throw them into militarized prisons. Their President now has a 90%+ approval rating, and is one of the most well regarded leaders in the world. Obviously there's a 'First they came for the Communists, And I did not speak out, Because I was not a Communist...' type concern here. But in this case, it seems that first they came for the criminals, crime plummeted, and everybody lived happily ever after.
And again there are also completely reasonable human rights concerns, but the thing I think people often disregard in this calculus is the human rights of the literally 99% of people who were previously being terrorized, killed, robbed, and so on by the 1% of people. They have obviously rounded up some people who are innocent and they are making efforts to resolve that, and I hope those who are truly innocent receive fair compensation for the distress. But if one views human rights as a net (gains, versus losses), then El Salvador is vastly more humane than it was in the past.
