Not a Proof

Techdirt: "The company making the voting machines needs to prove that they're safe [...]
By handing it off to a single hacker, suddenly the assumption is that the e-voting machines are safe unless the hacker breaks into them.
So, should he not find a particular security hole, the company will start promoting that as proof that the machines are secure, when all it really means is this one particular hacker was unable to find a vulnerability."
