Medical Neglect Interpretation

From Alabama to Australia and nearly every point between, the grim global ledger reveals a brutal consensus: inside the walls, a prison sentence has become a de facto death sentence for treatable illness, where systemic neglect is the unindicted co-conspirator.

Physical Abuse

  • In US federal prisons, 8.6% of inmates reported physical assaults by staff in 2018 according to BJS data from over 50,000 surveyed inmates.

  • Virginia DOC 2022: 956 use-of-force events injuring 400 inmates.

Physical Abuse Interpretation

The grim arithmetic of global incarceration adds up to this: in too many cells, the badge has become a bludgeon, and the sentence handed down by the court is too often compounded by a covert and violent one from its keepers.

Psychological Abuse

  • Turkey 2022: 10,000 political prisoners in isolation cells.
  • BJS 2020: 37% jail suicides linked to isolation.

Psychological Abuse Interpretation

From Australia to Rikers, the data forms a damning global chorus proving that solitary confinement is less a tool of security and more a factory for manufacturing mental illness, self-harm, and suicide.

Sexual Abuse Interpretation

The grim arithmetic of incarceration consistently shows that the gravest threat to a prisoner's safety is not the population behind the bars, but too often the very individuals hired to stand guard in front of them.
