THE LECTURE
Last Friday, I attended a lecture in our university. The topic of the lecture named 'fighting crime with science'.
Nowadays a lot of science and technology were used into the fight for crime. Just like the surveillance system and CCTV. They are really helpful. Firstly, the lecture gave us an example of how the media help the police to find the student who killed his professor: The CCTV which is in the room where the violent took place saw the part of face of the student. After that the police found many things that the student had ever toughed and worn. So they got the DNA of the student in order to identify the killer.
Beside all above, we knew something more. There are many cameras around us. When we walk along the street or buy some food in the supermarket, we are seeing by some others. More and more people believe the surveillance system breaches their life.
So everything has two sides. Though the surveillance system is really helpful to the police and fight for crime, it can not keep the people far away from dangers.
From this lecture, I got a lot of knowledge of media and crime. Moreover, it really helpful to my listening skills for understanding lectures and talks.
