So there are people on Facebook and Twitter mistaking the Chechen terrorists, who are from Chechnya, for being from the Czech Republic LOL. It's led to some outcry against the Czech Republic that the ambassador had to tell everyone that the Czech Republic had nothing to do with all of this.
Aren't I glad I don't have a Facebook, Twitter, and Tumblr.
