> Unfortunately the NSA doesn't seem to use their resources to secure the nation, and just ignores all the large scale violent crime that goes on daily.

The NSA is part of the Department of Defense charged with foreign signals intelligence for national security purposes, its not a law enforcement agency. (And many of the tools it uses would be flagrantly unconstitutional if used for domestic law enforcement.)

Generally, blurring of the military and law enforcement roles is not a healthy thing; it may be good for order, but rarely for liberty.
