Not guilty is not the same as innocent.
NO, NO, NO... you have it ass backwards...
Guilt or innocence are questions that arise ONLY by reason of the operation of the laws of our legal system... if there are no such laws, then no issues of guilt or innocence can possibly arise.
Under this system, you are presumed to be
factually and legally innocent unless and until the processes of the system determine guilt reasonable doubt. And under this system the "quality" of your "innocence" is the same before and after a trial that finds you not guilty... because until you are found guilty by that process, nothing has changed in your status from what it was before the accusation was made.
If you don't like the system, change it... but you cannot, willy-nilly, pick which laws you accept and apply and which you reject and do not apply... that does violence not only to the system but to reason itself.
What you are saying is the same thing as saying all that you need is an allegation and you are deemed or held to be blameworthy, liable or responsible... by that standard, how could anyone ever establish that the accusation is false or without foundation?
If you wish to live in a system where once accused of something you have no way of escaping blame, then go ahead and create it... but leave me out of it! The system that we already have is stupid enough without it!
There is a "legal" expression that expresses this very succinctly: "You can't suck and blow at the same time"... Try working that out with your favorite sex partner!
