Not a clear cut (Posted on 2012-11-18) Difficulty: 3 of 5
I have slightly rephrased a problem found on the web (Steve Miller's page):

begin **

The police rounded up Jim, Bud and Sam yesterday, following the robbery of the local bank.
The three suspects made the following statements under intensive questioning:

• Jim: I'm innocent.
• Bud: I'm innocent.
• Sam: Bud is guilty.

If only one of these statements turns out to be true, who robbed the bank?

**end

Apparently, there are several solutions.
Find them.

The statements from Bud and Sam are conflicting, thus one must be true and the other false.  Since there can be only one true statement, this means that Jim's statement must be false.  Therefore, Jim is guilty, and Bud's statement is the only true one.
