I wish Piers would be as concerned about America's incarceration rates as much as he is our gun murder rate. I find our incarceration numbers are far more depressing for such a 'free' nation.
Justice is harsher in America than in any other rich country. Between 2.3m and 2.4m Americans are behind bars, roughly one in every 100 adults. If those on parole or probation are included, one adult in 31 is under “correctional” supervision. As a proportion of its total population, America incarcerates five times more people than Britain, nine times more than Germany and 12 times more than Japan. Overcrowding is the norm. Federal prisons house 60% more inmates than they were designed for. State lock-ups are only slightly less stuffed.
