Answer:
Defamation, and she will win the suit.
Explanation:
Defamation refers to a false or misleading claim made by a party about another party, which harms or damages their reputation. The target of defamation can sue the offending party for this and demand a compensation.
Most states in the United States recognize the concept of defamation per se, that is, false statements that are inherently defamatory and that injure the reputation of the offended party, like accusing someone of committing a crime. What the plaintiff has to do to win a defamation suit is prove that the statement was made, that the statement was false, and that the person who made the false statement shared it with a third party. In our case, Caldwell was falsely accused of stealing by the security guard, and at least another store employee had knowledge of the situation. This fulfills the criteria needed for Caldwell to sue for defamation and win the suit.
