And he hasn’t even been suspended from practicing law, much less disbarred. He’s now working as a defense lawyer in private practice. That’s right: he’s making a living representing people accused of crimes, in the same courthouse from which he was (supposedly) banished a year ago. His law firm website even touts his experience as a “former homicide prosecutor.”

The law also makes it virtually impossible for Mr. Kurtzrock’s victims to sue him, with the Supreme Court having declared that individual prosecutors and their offices are “immune” from civil rights lawsuits in all but the rarest of cases.

Mr. Kurtzrock’s case may be the most recent example of the system’s egregious failure to hold a rogue prosecutor accountable, but it’s hardly anomalous.

The National Registry of Exonerations, based out of the University of California, Irvine, reports that “official misconduct” — by police, prosecutors or both — was a factor in roughly half of the nearly 2,200 exonerations across the country since 1989.

To date, only one prosecutor in the country (Ken Anderson, who withheld exculpatory evidence from my former Texas client Michael Morton) has ever been jailed for misconduct causing a wrongful conviction. And Mr. Anderson served just eight days in the county jail — starkly different from the 25 years that Mr. Morton languished in state prison.

That’s true even when prosecutorial misconduct taints thousands of cases.

Last June, a Massachusetts judge issued a blistering 127-page decision finding that two former assistant attorneys general had committed “egregious misconduct” and “fraud on the court” in failing to disclose evidence that a former state lab analyst was addicted to drugs while on the job for years. After five years of litigation, the state has agreed to throw out more than 8,000 drug convictions tainted by laboratory and prosecutorial misconduct.

The lab analyst served 13 months in prison for her crimes. But the former prosecutors? Neither have faced criminal charges, and both are still licensed attorneys. Indeed, even though my office filed formal complaints against them in July 2017 the Massachusetts Bar has yet to even hold a public hearing on their law licenses. And both have found other jobs as senior government lawyers, their salaries funded by taxpayers.
