The shameful thing is that individuals who do that spying imagine that they have the right to do it but others don't.
Most people say privacy is a basic right of civilized society, but you have some scoundrels who are drunk on a high paying job and fantasize that their superior government job or some other fiction gives them extraordinary rights.
The root cause is hiring too many people to do too little work. If you hire 10,000 people to do a job that requires only 5 people the extra workers will get into mischief. It's why police officers rape and steal, government police spy and also why our foods are filled with additives and chemicals
Stupid people who don't know how stupid they are trying to force their stupidity on others.
