Five suspects are called into police headquarters for questioning.
They give the following statements.
A: "One of the five of us is lying."
B: "Two of the five of us are lying."
C: "I know these guys, and three of the five of us are lying."
D: "Don't listen to a word they say. Out of the five of us, four of us are lying."
E: "All five if us are dirty rotten liars!"
The police only want to release the suspects who are telling the truth. How many people should they let go?
