RAKOFF: Here's Why Judges Blindly Approve Plea Bargains - Even When They Put Innocents In Jail

In his essay in The New York Review of Books, Manhattan federal judge Jed Rakoff explains why it's problematic that 97% of federal criminal defendants agree to plead guilty if their cases aren't dismissed.

With so many people pleading guilty, some innocent defendants invariably sign onto plea bargains just to avoid the prospect of lengthy prison sentences. These are often poor defendants who aren't optimistic about winning at trial and face intense pressure from prosecutors to enter a plea.

Despite this problem, judges very rarely reject plea bargains. That's because "they don't really have any familiarity with the underlying facts," Rakoff told me over the phone recently. Even a "conscientious judge" wouldn't have enough information to drill both sides about the plea agreement, he said.

Here's what happens when defendants plead guilty, according to Rakoff: the accused reads a statement with the "bare bones of what he has decided to admit to," while prosecutor reads a statement indicating what they're prepared to prove. The judge will advise the defendant of the rights he's giving up - such as the right to a trial.

"All of this has been worked out beforehand so that it all goes very smoothly ... yet it tells the judge nothing but the very basic facts," Rakoff said. "...The whole thing takes about 20 minutes."

This scenario wouldn't make it very easy for a judge to spot a false confession. In his essay, Rakoff shed some light on just how many of these plea agreements might involve false confessions. First, he pointed out that of the roughly 300 people cleared of their crimes by the Innocence Project, about 10% had originally pleaded guilty.

Criminologists have estimated that between 2% and 8% of felons who pleaded guilty were actually innocent, Rakoff wrote in his essay. Even assuming that number was 1%, Rakoff points out, that's still a lot of innocent people behind bars.

"When you recall that, of the 2.2 million Americans in prison, over 2 million are there because of plea bargains," Rakoff writes, "we are then talking about an estimated 20,000 persons, or more, who are in prison for crimes to which they pleaded guilty but did not in fact commit."
