402.04 BURDEN OF PROOF AND RELATED MATTERS
The charge of any offense is not evidence, and it creates no inference that any offense was committed or that (the) (either) (any) defendant is guilty of an offense.
(The) (Each) defendant is presumed to be innocent, unless and until, during your deliberations upon your verdict, you find him guilty. This presumption of innocence places upon the state the burden of proving beyond a reasonable doubt that (the) (either) (any) defendant is guilty.
A reasonable doubt is a doubt based upon reason and common sense after careful and impartial consideration of all the evidence in the case.
Proof beyond a reasonable doubt is proof that leaves you firmly convinced of the defendant’s guilt. The law does not require proof that overcomes every possible doubt. If, after your consideration of all the evidence, you are firmly convinced that (a) (the) defendant is guilty of the offense charged, you will find him guilty. If you are not so convinced, you must give him the benefit of the doubt and find him not guilty.
