What Snowden did was technically illegal
For the record, what every single one of the Founding Fathers of the United States did was "technically illegal", too.
Boston Tea Party? technically illegal
Rosa Parks technically illegal
Susan B Anthony? technically illegal
Martin Luther King, Jr? technically illegal
So, Ms Lisa Monaco, go jump in the motherfucking sea. You suggest that the "right way" for Mr Snowden to react to finding that his government was doing illegal shit would be to "speak out about it. Well, madame spokesperson, how the fuck do you "speak out" about something that it's illegal to disclose?
Was Snowden supposed to go on the Sunday talk shows and say, "the government is doing really sleazy, illegal and unconstitutional shit, but I can't tell you what it is"? They'd have laughed at him.
