Re: In essence, the GAO study makes it clear that no bank, grocery store or mom & pop chop shop would dare operate its business on a computer system as flimsy, fragile and easily manipulated as the one on which the 2004 election turned.

Not true. Almost every major organization has significant flaws in their computer security (user passwords are just one example). Minor organizations like mom and pop stores are likely to have far more security problems than the voting machines did.

Banks might do an ok job, but the other organizations wouldn't.

Just notice how often that windows (sic) comes out with security releases that you need to install to avoid someone gaining possible control of your computer (Eg a total security breach). It's about once a month.

The more complex a computer system is, the more likely there is to be a major security flaw. Most of them just don't get noticed, because you'd have to stumble into the flaw (get lucky).
