Now why don't you ask other people in electric prison what they did and why they are there. My answer is I have done nothing whatsoever and can prove it. In court of law!

I don't know who keeps saying stuff about me, and not 10 years old, so I'm gonna say this 1 time.........Do NOT!!!! Threaten me or my family or try to ruin the only way I can make money right now. First of all you know nothing about elctromagnetic prisons. I've done nothing wrong and have been held here and tortured my entire life. Can't go get an education so I need to figure this stuff out myself. I believe Steve Morris does understand this and has agreed to help me some. But if I hear one more time any type of threat against me or my family or threaten my business I'm gonna find out who you are and kick your ass all up at down the street, so DONT DO IT. And by the way someone also gave my mother cancer!!!!!!
