You Asked About: How To Spy On People

Why do people spy against their own country?

We see it on TV all the time people in the US government spying but why? How could someone turn on their own country? How does someone be recruited to spy and gather information for another country? If i work at the FBI and i refuse an higher position because it requires and lie detector test shouldn’t that be a sign that that person could be passing information to a foreign government? Think about it how many people would turn down an promotion or pay raise? and why do it take our government so long to find Americans passing information to other governments? And should people who sell information to other government be executed or go to jail for the rest of their lives?
