Is it OK for governments to spy or monitor citizen's communications & activities?
The big reveal that United States government monitors all the communications (online & telephonic) caused a havoc in the tech media. The governments justify doing it by saying that it's crucial for the national security. At the same time, it's direct breach of one's privacy. Basically - any communication that you have with your friends, closed ones which you think should be completely private - isn't.
Do you think the governments are justified in monitoring / spying activities and communications of citizens? Provide reasoning to back your points.
