I have written often about prosecutorial misconduct and how rare it is to see accountability on the part of prosecutors who engage in it. (Go here and scroll down for my posts on this.) For this reason I recommend you go read an article by United States District Judge Frederic Block of the Eastern District of New York in which he argues it’s time to end the notion of absolute immunity for prosecutors. You should read the full article here.
Simple Justice has a comment on the article here.
