Billy and Stanley agree they will commit a bank robbery. They buy some guns, masks and bags. They later have Billy's girlfriend Brenda drive them to the bank. Not until they are on their way do they tell Brenda what they are doing and give her instructions to drive by the bank; drop them off down the road, and wait in the car for them, in the alley. Brenda agrees to help. But, after Billy and Stanley get out, Brenda drives off to the alley where she is supposed to wait, but instead gets cold feet and goes home.

However, an alert police officer watched them drive by the bank with Brenda at the wheel. He watched Billy and Stanley walk to the bank. The officer then saw what he thought was a gun in Stanley's waist. The officer decided to "stop" Billy and Stanley, and yelled at them, as Stanley was grabbing the door to go into the bank. Billy and Stanley immediately run away. Billy was caught by the officer, 3 blocks away. Stanley ran to his girlfriend's, Susan, house. He told her what happened, left his gun and other bank robbery items, and drove 500 miles away, to his mom's.

Billy gave up everybody, including telling the cops that Stanley likely went to Susan's. Susan lied to the police who got a search warrant and found the items Stanley left.

Define the following terms: Conspiracy, Abandonment & Withdrawal, Attempt, accomplice, and aider & abettor, and discuss the potential criminal liability or not of Billy, Stanley Brenda, and Susan, in light of those crimes at common law.
