"Kevin Jensen"

"Independence, U.S.A."
A Soviet-era black ops project to plant Soviet and later, Russian agents into North America. The idea is that they are trained and then altered to look exactly like personnel at U.S. intelligence agencies or power plants. They kill the real person, then commit a terrorist act (like meltdown a nuclear power plant). When the authorities show up, they find the body of the original with a "suicide note" claiming responsibility for what happened. So not only are those people murdered and replaced but are disgraced with their families thinking they were responsible for the deaths of innocent people.
"Operation Davenport"
The idea that a rogue hacker would steal a very sensitive key to hack the internet.
