Make comparative summary on the following case:

Sixteen-year-old Elwood Blues went into the Kwik-e-Mart, a convenience store close to his home. He walked all around the store looking for his favourite brand of cookies. He didn't find what he was looking for and was about to leave the store when he found his way blocked by the clerk, a husky man named Steve Barnes. Barnes said, "You put something into your pocket!" Elwood replied, "No, I didn't." "We'll see about that!" Barnes said. Barnes then told Elwood that he was making a citizen's arrest, called the police, and told Elwood that he couldn't leave the store until the police got there.

Barnes stayed in front of the door until the police arrived, blocking the store's only exit. When the police arrived, Barnes told the officer, "I think this boy shoplifted something from my store and put it into his pocket." The police officer asked Elwood for his side of the story. Elwood said, "I didn't take anything. See?" and emptied his pockets. There was nothing belonging to the store in his pockets, so the police officer told Elwood he was free to go. Elwood left. Elwood and his parents have now come to your firm because they want to know whether Elwood can sue the store for every nickel it's got for the way he was treated.
