When is a joke not a joke? When the police say so.
This seems to be the indication in the case of Justin Carter -- 18 years old at the time of the alleged incident -- who has reportedly been sitting in a Texas jail since March.
It all began after a game a "League of Legends." An argument is said to have spilled over to Facebook.
During this argument, Carter was allegedly accused by another gamer of being insane. Gamers say those kinds of things.
