Read these e-mails from Diebold. Their ONLY concern is making the sale (of the voting machines), and if it involves hiding the security problems from the customer, so be it. If you have been in business, you will see in these e-mails that they are sales-driven, and you will be familiar with people with sales-driven attitudes. It’s natural they will see anyone complaining about problems with their product as pests and threats.
The e-mails show they (and who else?) have known about security problems for ten years — which means that ten years of elections handled by Diebold election machines are suspect.
