Imprisonment only yields the benefits of incapacitation if the offenders are a likely threat to society. If the criminal that is given an extensive prison sentence was unlikely to commit another crime, then his/her incapacitation did not actually protect society. Studies within prison populations demonstrate that most offenders commit relatively little crime, while a core group commits a large portion of the crime. For example, a Rand Corporation survey found that half of all burglars committed fewer than six crimes per year, while the top 10% committed over two hundred. [1] Thus society is not particularly well serve when the bottom half of burglars face long prison sentences; few burglaries are avoided, and these criminals will now have more difficulty rejoining society.
