Statute of Limitations on Torture

Looks like the statute of limitations has run out on those who "tortured" the terrorists.

The Statue of Limitations for federal offenses is spelled out in Title 18 Section 3282:

Except as otherwise expressly provided by law, no person shall be prosecuted, tried, or punished for any offense, not capital, unless the indictment is found or the information is instituted within five years next after such offense shall have been committed. 

In other words, unless someone was killed all prosecutions must be brought within five years.

So why in the world are we spending money to investigate the "torturing" of terrorists that happened before 2004?
