These are my thoughts on the crime files
High School Hacker
There are so many things that are wrong here. First off, he used passwords, stolen from teachers, to hack into the school network. Then he changes his grades and his friends grades. So then he installs MALWARE so he can get on anywhere else. He most likely did this to have better grades for him and his friends. His friends were the most affected by this problem because he changed their grades.

Malicious IMs
Well, i think this is stealing. This 19-year-old hacker wants credit card numbers, money, and identities. So since this is fake and when people get it by their friends, they actually think it's them trying to show them something.

Roaming Robots
I think that the entire corporation should get in trouble. The second company is paying him to do this and its wrong. Every one's computers are probably covered with pop-ups and viruses.
