Columbia, SC — All countries constantly engage in spying on other countries, friend and foe alike. The purpose of military attaches assigned to embassies is overt intelligence collection.
Also, there is universal covert intelligence collection. Two U.S. agencies with that mission are the CIA and the NSA. In order to accomplish their mission, it is sometimes necessary to “spy” on U.S. citizens. That’s done, as is all other intelligence gathering, for the purpose of national defense. To be most effective, its methods must be kept secret.
Let’s prosecute Edward Snowden and quit making political hay over privacy and offending allies.
