This article leads me to wonder. Has the US Government ever requested the master private keys for the main certificate authorities, such as Verisign? It actually makes sense in a criminal investigation to spoof a real site in order to phish for passwords or the personal information of criminals. A similar method was used before to get cable thieves to call a phone number on the screen thinking they were giving their information to win a free item. However, having the capability to impersonate any company, group, or individual has an enormous potential for abuse.
