Silly goose, you with your phancy photons.  You need to secure the
communication between the stadium and local police?  Set up a VPN.

Oh I see, a wealthy patron of the black arts.  By all means take his
money, this is how the arts advance.

Pretty funny right?  AES-128 is plenty strong for what they're doing,
even without dedicated fiber.  Hackers aren't going to try cracking the
crypto anyway, they'll focus on cracking the entry points into the
system.  Even people in government would rather strong-arm someone (e.g.
a certificate authority or other private key holder) before trying to
crack any crypto.
