How do you "[look] at the results achieved by other countries" if those results aren't reported?

It's a fairly common sentiment that the U.S. penal system is heavily skewed toward retribution than reformation.[1] But identifying a problem on the one hand, and quantifying and addressing it on the other, are two entirely separate tasks. The latter is typically much more difficult.[2]

[1] Justice Anton Scalia admitted as much in court, "Well, I thought that modern penology has abandoned that rehabilitation thing, and they--they no longer call prisons reformatories or--or whatever, and punishment is the--is the criterion now. Deserved punishment for crime." Oral argument, Miller v. Alabama, 2012.
