The Last Mile's website (https://thelastmile.org/about/) lists not 100 graduates, but 240 "returned citizens" who have successfully rejoined society, still with a 0% recidivism rate. This article said they only have 100 or so graduates, and the article was published in January of last year.
Assuming the article's graduates are the same thing as the website's returned citizens, that means that The Last Mile has managed to produce about 1.4 times more graduates in the past year than in the entire previous 10 years combined.
Healthy skepticism is healthy, but to dismiss this program's meteoric rise, huge potential, and noble cause without even a cursory attempt to understand them is being intentionally obtuse.
