✗Key Problems

1.Early release of 38,000+ criminals due to capacity failure
2.10,500 foreign criminals not deported (12% of prison pop)
3.Crown Court backlog 74,651 cases - victims wait 3-4 years
4.Only 3% small boat arrivals deported - system collapse

✓Solutions

1.EMERGENCY CAPACITY: Build 10,000 prison places in 18 months (modular construction)
2.FOREIGN NATIONAL TRANSFERS: Returns within 30 days of sentence (EU precedent)
3.SENTENCING CLARITY: Minimum terms for serious violent/sexual offences (US federal model)
4.COURT CAPACITY: 150,000 sitting days to clear backlog (Nightingale courts model)

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
