He asks his friend Ronny to go to court as a witness for him and lie under oath saying that Jack was with him at his house the night of the robbery. He offers Ronny $1000 to come to court and lie. There were no surveillance cameras only the testimony of the shaken gas station clerk. This will give him an alibi. In addition to the robbery, Jack has committed what other crime with regard to his offer to Ronny? Define the crime.
