The President of the United States of America, Barack Obama approved the law to give to NSA wider powers, where the NSA is able to spy internet traffic in search of hackers, responsible of attacks against the US. The Justice Department permitted the spy agency to track online activities to recognize patterns related to malicious activities that the NSA could trace back to foreign state-sponsored hackers. The good news is that this week was voted a law to limit the power of the NSA and their spying program, which marked the first time since 9/11 that a law came out to restrict surveillance.”]
