Prosecutors would not get so many wrongful convictions if defense
attorneys did not plea bargain so much and actually learned to
litigate and catch the prosecutor doing wrong things.
A buddy of mine build a career helping defense attorneys win
their cases, simply by showing them how to do a competent job of
dealing with incompetent prosecutors. He says he has assisted in
over 750 cases and won 90% of them.
This reality should tell you that plea bargains make no sense in
the majority of cases because the defendant could beat the
prosecutor with a competent defense attorney, especially one
backed by my buddy.

The registry's founders say the numbers, which do not include many cases in which innocent suspects plead guilty to avoid the risk of more serious punishments or cases that have been dismissed because of legal error without new evidence of innocence, represent only some fraction of the problem in the nation's criminal justice system. "What this shows is that the criminal justice system makes mistakes, and they are more common than people think," said University of Michigan law Prof. Samuel Gross, the registry's editor. "It is not the rule, but we won't learn to get better unless we pay attention to these cases." Despite the data, the registry concluded that the "overwhelming majority of convicted defendants are guilty."
