American agents can steal, torture, kill, traffic drugs, et cetera, et cetera, and American agents are not arrested nor persecuted. A civilian makes a statement saying that the American Government is spying on ordinary people and suddenly all hell breaks loose. Are those in charge of American security agencies mentally retarded? Are the political officers who oversee the actions of American agents deranged?
If anything, the American authorities can create a scandal out of nothing. So, a contractor says that the Government is spying on ordinary citizens. We have known about it for ages. No need to issue threats, no need to go on the offensive. By trying to kill a fly with a cannon ball the American authorities have covered themselves in mud that merely confirms that they are up to no good.
