Half of 54 is 27. But only 26 prisoners in Oklahoma have been executed since 1990. Obviously not all agree with Macy's sense of logic. State and federal courts have overturned at least 15 Oklahoma County death penalty cases, all prosecuted during Macy's tenure as district attorney. Often the problem cited in these overturned cases stemmed not from legal technicalities or changes in the law, but from flagrant examples of prosecutorial misconduct by Macy during trial.
Prosecutorial misconduct is nothing less than cheating to win.
And, cheating serves no good purpose, especially in matters of life and death.
