MAJOR CAVEATS
- •Certainty of punishment matters more than severity - but UK has 6% charge rate, undermining both
- •UK incarceration rate (130/100k) far below US (500+) - diminishing returns argument less applicable
- •Rehabilitation vs incapacitation: contested evidence, but early release schemes have increased reoffending
- •Court digitisation risk real: HMCTS Common Platform has had significant problems
- •Prison capacity constraint genuine: 99% occupancy means early release regardless of policy intent
- •Police solve rate (6%) is the binding constraint - more prison places useless without arrests
- •"Root causes" framing often becomes excuse for inaction; enforcement and social policy not mutually exclusive
