Cops murdered my brother so what do I do now?

I offered one millon dollars for the cops to take a lie detector test and they said "No." It is because I saw cops murder my brother and I caught their lies on how they covered up his death! I was almost killed too, but luckily I hid underneath my dad's truck. I don't care about the money, I don't care if the entire police department is fired, my brother and I just wanted to be treated like a Human Being and in this book, it explains how I am going to do that. There is some profanity inside the book, but it because of all the anger I was feeling at the time. I won't seek revenge through my fist, I will seek justice through my book.
Every dollar that I make off this book is going to a cancer charity so don't think I am trying to make money off my brother's death. I wrote the book to explain the truth and how the police department covered up my brother's death.
