that's a pretty naive viewpoint. they could've just as easily built the facility on a military base... then what ? trying to prevent espionage through limiting access to resources is a very ineffective way...

another point is that the law won't seem to have any effect (even if it passes by the way - no guarantees on that) on the current installation until 2021... 7 years is a pretty long term to revert a bill or make new legislation that allows other options...

afaik (I'm not a us citizen) federal law supersedes state law in the US. So it follows that you need to have federal safeguards against wiretapping and whatnot... state legislation is cute at best but seems ineffective.
