School Lockdown
Personally, I think that this teacher had quite an overreaction – it’s just a computer that messed up! Of course, the school had to be careful as there’s lots of sensitive information on their servers, but shutting them down seems way too over the top. Why would someone want to hack a school system, anyway?!
Maybe they thought someone would try to change the kids’ school grades or something. Either way, it just goes to show how poor the school’s security system is if a simple mouse receiver could mess things up. How did the teacher not notice the thing sticking out of her PC?!
