The legal battle between the US and Dotcom started in sync with the January 2012 raid. Back then, Dotcom was charged with five criminal counts in the US: conspiracy to commit racketeering, conspiracy to commit copyright infringement, conspiracy to commit money laundering, and two counts of aiding copyright infringement.
A month later, a superseding indictment expanded the counts to 13, adding charges of racketeering, wire fraud, more counts of copyright infringement, and aiding and abetting copyright infringement. (Racketeering is a catchall criminal charge often associated with cases involving organized crime.)
Of those charges, which offenses fall under the extradition treaty between the United States and New Zealand? Currently, only two: racketeering and money laundering. Absent those charges, the US would have an even harder time trying to get Dotcom extradited.
Etc.
