Other Federal Agencies Want Access to Data NSA Compiles

Want surveillance to help track everything from drug trafficking to copyright infringement

The National Security Agency's dominant role as the nation's spy warehouse has spurred frequent tensions and turf fights with other federal intelligence agencies that want to use its surveillance tools for their own investigations, officials say.

Agencies working to curb drug trafficking, cyberattacks, money laundering, counterfeiting and even copyright infringement complain that their attempts to exploit the security agency's vast resources have often been turned down because their own investigations are not considered a high enough priority, current and former government officials say.
