If you were worried about wrongs performed in that courtroom you'd crawl back to the justice system on your hands and knees and beg them to try you again with a grand jury and a judge that doesn't omit legal statutes to give you a leg up you lying sack of crap.
After being told to stay put you got out of your car, chased someone down who ran from you in terror, and brandished a gun while they held nothing more threatening than a bag of candy and a cell phone for no other reason than being out on a public sidewalk. Not skulking in the dark, not hiding in a bush, not on private property: On a sidewalk headed home. After your attempt at playing vigilante quite predictably went to shit you proceeded to make a wild story about a humanly impossible feat of sprinting, bushes that didn't exist, and attempts to grab a gun that only had your fingerprints on it from the completely concealed internal holster neither of you would have been able to reach if you were flat on your back like you claim. You also refused to go to the hospital and cops that should have known fucking better decided not to make you go under police escort depsite there being a shooting. They wrote it off as an attempted mugging despite having you recorded on audio leaping out of your car to physically restrain him without any legal ability to do so and considered the matter closed before even learning the dead kid's name and that his father was three blocks away expecting him to come home. You are not an innocent man and it horrifies me the Supreme Court didn't jump off their collective bench and shout bullshit when the unconstitutionally undersized jury reluctantly let you walk based on irregular instruction.
You should go ask O.J. for tips on writing your memoirs. Maybe you could go on a nice walk together and pick out a pair of driving gloves for each other before you get down to business.
