Input: CONTEXT: For the same reason that Jeff doesn't immediately call the police with his suspicions: fear that if Thorwald realizes he has been made by an outside observer, he will dispose of all the evidence and escape without prosecution... Lisa is buying more time by being taken under arrest, and the event was intended to appease Thorwald to some extent. He was already making mistakes (retaining his wife's wedding ring due to sentimentality), and Lisa was clinging onto the thought that their plan was not yet foiled. The arrest itself was actually a means of getting Lisa safely out of the apartment, and of getting the wedding ring (as evidence) into the hands of the police.  <sep>  Q: Why didn't Lisa tell the truth about Thorwald to the police? A: fear that if Thorwald realizes he has been made by an outside observer, he will dispose of all the evidence and escape without prosecution 
Output:
Why did she get herself arrested?
