Incorrect, let me reiterate: given the definition Innocent: free from legal guilt or fault, what is the difference between 'innocent' and 'not guilty'?
They are the same, for if you are "not guilty"* you are free from legal guilt... and if you are "innocent"* then you are also free from legal guilt.
Is this not the case?
* -- Your definition.
In court you will be found guilty or not guilty.
You will not be found innocent.
