Catch the Thief<br>The police were trying to catch a neighborhood thief. They decided to stake-out the entire area that night. They didn't catch the thief so decided to continue the stake-out. Four nights later they saw the thief. All the police officers rushed to grab the guy and they caught him.
The police did not try a different tactic after the first night.
I used a negative to confuse the system. The police used a stake out approach all the nights, so this is a correct statement.
