DHS in Little brother

The story was pretty much talking about the problem with the Department of Homeland Security of the United States. One day, there was the terrorist attack by bombing Bay Bridge in San Francisco, CA. The main character was Marcus who was the smart kid that knows very well how to operate with a computer and networking stuffs. He liked to play online game with four other friends. He had three important friends that had been mentioning throughout the story and witnessed all the dirty method of DHS investigation to find the terrorists who responded for this attack.
One day four of them decided to skip the school, so they could find the clue which was the part of their game, and then something happened. Some terrorists attack happened, four of them were trying to escape to the ground level. The crowds were so thick, so they decided to go out from that spot to the above. One of Marcus’s friends got stabbed and bleeding. Marcus was trying to stop cars to get some helps, but instead, all four of them were kidnapped by the group of army. They were later found out that they were sent to the prison and being interrogated by the US Department of Homeland Security. They went to hardship during investigation by guards, and were released after five days. Unfortunately, one of his friends was missing. It seemed that he might be dead.
The homeland security was mentioned throughout the story, and there were people who took side with the government and some people did not. Marcus was one of them who turned against government methods of security. He mentioned that every innocent people were being asked and questioned about abnormal pattern way of life. If something that you do that differed than usual, the police could come to you, be suspicious about you, and, for the worse case, you could be accused of being terrorists if you or any citizen do not cooperate.
When Marcus was during interrogation in prison, he was forced to tell his private identification, password for his email, phone etc. He had no choices but to tell everything to them to exchange with his freedom, wishing to be released from this place with his parents. After he went home, he found out that his laptop were being opened and modify with some secret surveillance device inside. He was doubted in the government security system and wanted to exploit their bad system.
The story talked about privacy matters. Everything was being watched through surveillance cameras. Even in Marcus’s school, there were many surveillance camera placed on every part of the school, so the school could track down if the students were trying to escape from classes. The camera was being able to identify people by watching the movement. The story also mentioned about XNET where Xnetters were being surveillance while in chatting conversation. Government was trying to find the suspicious conversation, so they could find who actual terrorists are.
The questions were split into two. One group thought that being excessive surveillance were a good solution for solving the problem, and another group who thought that being this many level of surveillance were way too much and intrude individual privacy. Almost everything were being watched and questioned from what we are doing which gave people less freedom. Instead of being secured by the government, people were uncomfortable and afraid more about terrorists.
In my opinion, I think that I agree with Marcus that being surveillance on everything was not the good idea to the solution. It’s rather waste of time and money if the government were too excessive of their security measurement. We never know if the terrorists will ever attack again. But then again, if we don’t do anything, it would be too valuable for them to attack us again. I think we should do that in appropriated amount of security measurement. Not like being watched on everything. People don’t have time for that.
