Recently, the hacker group "Lizard Squad" has attacked the xBox Live network and Playstation Network. This is not the first attack they have used against online gaming. While to many this may seem to simply be a disruption for people playing online games, this could potentially be a threat to credit card information linked with online accounts.
Allowing Americans to be attacked in any way--in this case, a cyber attack--is not acceptable, and the people who commit these actions should be reprimanded. For this reason, "Lizard Squad" and any foreign group who condones online attacks should be declared a terrorist group, and added to the terrorist watch list.
