I‘m no fan of security theater, or of the militarization of the police, or of post-9/11 panic-stoking by the news media. But when there‘s even a remote possibility of an attack, however small or improbable, on two branches of government, overreaction is warranted. The scenarios portrayed in movies like White House Down and Olympus Has Fallen do not happen in real-life, until such a day that they do.
