"Innocent Until Proven Guilty

First, it should be pointed out that if you did it, you're guilty, no matter what. So you're not innocent unless you're truly innocent. However, our system presumes innocence, which means that legally speaking, even the obviously guilty are treated as though they are innocent, until they are proven otherwise.

The concept of the presumption of innocence is one of the most basic in our system of justice. However, in so many words, it is not codified in the text of the Constitution. This basic right comes to us, like many things, from English jurisprudence, and has been a part of that system for so long, that it is considered common law. The concept is embodied in several provisions of the Constitution, however, such as the right to remain silent and the right to a jury."
