A group of technicians were commissioned by the State of California to test the security on the newly mandated electronic voting machines.
The technicians succeeded in cracking all of the machines, most of them rather easily "using standard home or office equipment". They have drafted two reports, one describing what they did that will be released to the public, and another that includes the methods they used. The latter will only be released to the California politicians.
That is a bit like keeping the secret from the chickens while telling the fox how to get into the hen house, isn't it?
