根据短文理解,完成下列表格。

    Jane was on her way home at around 6 o'clock. It was getting dark. As she drove into her community, she noticed a man.

    She saw the man walking along the sidewalk next to some houses. He didn't live in any of those houses. She had seen this man several times before. He looked like a criminal (罪犯).

    She drove by him. He looked at her car as she drove by. She continued driving and watched him in her rear view mirror (后视镜). She got to the corner and stopped. She continued to watch him walking in her direction. Suddenly, he turned left up a driveway (车道). A red SUV was parked in the driveway right next to the sidewalk. She saw him walk up to the driver's door and put his hand on the handle (把手). Then he returned to the sidewalk and went on to walk in her direction.

    "What is that all about?" Jane wondered. Then she realized that he had tested the door to see if it was locked. "He is a criminal," she thought. "That's what he does. He just walks in our neighborhood looking for cars to break into."

    She called the police and described the man. The police officer said he knew who the man was. The people in the community called two or three times this week to report him walking by. But the police couldn't arrest him for walking around unless they caught him with stolen things. "But he was testing that SUV door to see if it was unlocked," she said.

    "I'm sorry," said the officer. "That's not against the law. If you see him actually steal something, please give us a call."
