The indictment or formal charge against any person is not evidence of guilt. Indeed, the person is presumed by the law to be innocent. The law does not require a person to prove his innocence or produce any evidence at all. The Government has the burden of proving a person guilty beyond a reasonable doubt, and if it fails to do so the person is (so far as the law is concerned) not guilty.
Legal Definition of 'Innocence, Presumption Of'
The government has the obligation to presume innocence. You and I are free to presume what we like.
