This is an odd essay, because it spends a great deal of time justifying the part of the system prosecutors have nothing to do with, namely the mere existence of law, including criminal law, and no time justifying any of the things that prosecutors actually do. How does he deal with the necessity for constantly turning his blind eye to small-scale police perjury? How does he deal with the immense industry in useless narcotics incarcerations? How does the endless parade of youngsters who could have learned and been successful if only their dyslexia had been treated (78% of the defendants prosecuted by one ADA in the Bronx who paid to have them tested out of his own money, for example) affect him? All this "keeping the streets safe" crap only goes so far, really.
