US Constitution

“But there's a number of reasons why you should not enter not guilty plea the first day you go to court. Number one, you don't have to. It's still America. You are still innocent until proven guilty. So, you are already considered not guilty when you go to court. Anytime you go in pre-sentencing, you are seen or you should be seen as not guilty because it is your right to be treated as not guilty because you have not been sentenced or taken a plea. So, you don't have to actually formally assert that you're not guilty. It is presumed under the US Constitution.”
