Computers can be hacked.
True.

The government uses computers.
True, but with far more advanced programming than the public has access to.

These computers are protected by security (I'm referring to guards, cameras, and office buildings here, as opposed to firewalls and antiviruses and the like).
And the ones the government has are much better than the ones most people have.

If the security can be bypassed, government computers can be hacked.
Possibly. But very unlikely.

By the way, Blade, you posted links to PressTV, The Right Perspective, Land Destroyer Report, Before Its News, and Poitics.ie as "proof" that people were concerned about this.

Bull... shit. Why not the National Enquirer while you're at it? If there were something about this on CBS News' website, or the website for fot The New York Times then that would be proof. I'd even give this a second thought if it came up in BBC News. But not in websites like that.
