It is an important part of US law. In conspiracy cases, individuals may be prosecuted in any district in which an overt act in furtherance of the conspiracy occurs, by any of the conspirators. In this case, some of his alleged co-conspirators trafficked drugs in Kansas.

In weev's case, the court rejected New Jersey as venue because no overt act in commission of the crime occurred in New Jersey, since neither weev nor the AT&T servers were in the state. The prosecutors argued that NJ was proper since many of the victims (AT&T customers) were in New Jersey, an argument the court didn't buy.
