Prosecutorial misconduct.
Hiding evidence, misleading juries — documented at scale in the cases we know were wrong, and punished almost never. The other half of the accountability story.
Prosecutors hold the most unchecked power in the justice system — and when they cross the line, the near-universal outcome is nothing. The Michael Morton case is famous precisely because it's the rare exception.
Every figure is FACT, pinned to the Death Penalty Information Center, the National Registry of Exonerations, and the court record; the impunity is structural, starting with absolute immunity.
The Death Penalty Information Center identified more than 550 capital cases reversed for prosecutorial misconduct or ending in a misconduct exoneration since 1972 — over 5.6% of all death sentences imposed in that span, across 228 counties and 32 states plus federal prosecutions. The most common forms: withholding favorable evidence (35%) and improper argument (33%). And that's only the cases where a court refused to call it 'harmless.'

The National Registry of Exonerations' 2020 report, 'Government Misconduct and Convicting the Innocent,' found official misconduct in 54% of the exonerations it studied — and in a large majority of murder exonerations. Concealing exculpatory evidence (a Brady violation) is among the most common prosecutorial forms. DPIC separately found 69% of death-row exonerations involved official misconduct.

Michael Morton: 25 years for a murder he didn't commit, while the evidence sat in a file.
Morton was convicted in 1987 of murdering his wife Christine and sentenced to life. Prosecutor Ken Anderson never disclosed the exculpatory evidence: a transcript in which the Mortons' 3-year-old son said 'a monster' — not his father — killed his mother; neighbors' reports of a man in a green van behind the house; Christine's stolen purse and fraudulently used credit card; unidentified fingerprints and a footprint. DNA testing — which the DA's office fought for six years — freed Morton on Oct. 4, 2011, after nearly 25 years, and identified the real killer, Mark Alan Norwood (later convicted of Christine's murder and a second, similar killing).
The rare accountability — and why it's the exception that proves the rule.
A Texas court of inquiry found evidence Anderson had concealed the exculpatory material and tampered with evidence. In 2013 he pleaded to criminal contempt, gave up his law license, was ordered to serve jail time and 500 hours of community service — widely described as the first U.S. prosecutor jailed for this kind of misconduct. Texas then passed the Michael Morton Act (2013), requiring prosecutors to open their files to the defense. That this made national news is the tell: for the hundreds of documented misconduct cases, punishment this real is extremely rare.
Why accountability is near-zero: absolute immunity, and bar discipline that almost never comes.
Since Imbler v. Pachtman (1976), prosecutors have absolute immunity from civil suit for their conduct in the courtroom — even for knowingly using false evidence or hiding exculpatory material. State-bar discipline for prosecutorial misconduct is documented to be extraordinarily rare relative to the number of misconduct findings. So the ordinary consequence for even court-confirmed misconduct is a reversal (if the defendant is lucky) — not a sanction for the prosecutor. Absolute immunity = FACT (Supreme Court law); the rarity of discipline = a repeatedly documented pattern.
“This court cannot think of a more intentionally harmful act than a prosecutor's conscious choice to hide mitigating evidence so as to create an uneven playing field for a defendant facing a murder charge and a life sentence.”
How this page is graded.
- FACT: the DPIC capital-case figures (550+; 5.6%; 35%/33%; 69% of death-row exonerations); the National Registry's 54% official-misconduct finding; the Morton case and Anderson's contempt conviction, disbarment, and jailing; the Michael Morton Act; absolute immunity under Imbler v. Pachtman.
- ATTRIBUTED: the specific counts to DPIC and the National Registry (their databases and reports); the characterization of Anderson as the 'first prosecutor jailed' to the Innocence Project and contemporaneous reporting.
- NOT claimed: that most prosecutors commit misconduct, or a single national discipline rate; the point is that when misconduct is proven, punishment of the prosecutor is the rare exception.
Why it matters.
Read alongside the judicial-misconduct funnel, this is the same lesson from the prosecution table: the actors with the most power over a person's liberty face the least personal accountability when they abuse it. Judges are policed mostly in secret by other judges; prosecutors are shielded by absolute immunity and near-nonexistent bar discipline. The Morton case is the exception held up precisely because it's so rare — and the reforms it produced (open-file discovery) are the exception too. It anchors Judges & Prosecutors and frames The Untouchables and Policing the Poor, since it's overwhelmingly the poor and accused who bear the cost.
