Evidentiary rules allow a prosecutor to introduce testimony that tends to show that the defendants actions prove he knew he was guilty (at least of something). This is sometimes referred to as “consciousness of guilt”. For example, such evidence may include actions the defendant took to “cover up” his alleged crime. Flight, when unexplained, may indicate consciousness of guilt if the facts and the circumstances support it. A person's false statements as to (his/her) whereabouts at the time of the offense may tend to show a consciousness of guilt.
