In Miranda vs Arizona the U.S. Supreme Court ruled "any statement by the defendant could and would be used against the defendant in a court of law" and they should be warned of this fact. What is also true is any statement by the defendant could also be used for the defendant, very few defendants realize this.
The defendant in New Jersey Vs Forchion, INDICTMENT NO. 2010—08-0866-I, clearly does understand this. Forchion - aka- NJweedman made this video and mailed it to the Prosecutor and titled it "MY STATEMENT".
Forchion says he will introduce the video himself as a statement he made after his arrest along with other statements he made to the local press.
