hich describes differences between direct, real and circumstantial evidence

which describes differences between direct, real and circumstantial evidence.  Imagine you are a juror in a criminal case in which a defendant is charged with robbing a party store. Potential evidence the prosecutor hopes to introduce into the trial include:

• eyewitness testimony of the clerk that was robbed
• store security camera video showing the back of the robber
• DNA analysis results of the robber's blood that was left at the scene of the crime
• testimony of a neighbor who heard someone say that the defendant committed the crime 

Consider the above evidence and then rank the importance and reliability that you think each has in determining the guilt or innocence of the accused. Rank the most important #1 and least important #4. Justify why you ranked the evidence in the order that you did.
