The "problem" here is not secure communication. It is media propaganda / information warfare. Facebook and Twitter being used to instill hate and spread conspiracies. It is all in the open: Facebook images stating that Israel is behind ISIS, or Twitter accounts that post nothing but Anwar al-Awlaki videos. Could you imagine that happening 10 years ago, on your own homepage, without being raided? If Twitter can block porn, surely they can block terrorist propaganda too. But the law enforcement probably want to use these for fishing. Instead Clinton wants to build another nuke.
> "Dad, what happens if Donald Trump wins and we have to move out of our homes?"
These are propaganda tactics close to character assassination. In the next sentence he says that "freedom of expression" unites us, but when Trump uses this freedom of expression he is suddenly scaring Muslim kids. Very recognizable.
> especially from someone as untried and as incompetent as Donald Trump.
You just know that they made this a talking point, a hook. And O'Malley wrestled it in his answer, because that is what he prepared.
> where do you draw the line between national security and personal security?
Donald Trump is incompetent. Next question! Next!
