Sorry bro, but I have worked at a government entity before and have seen the incompetence first hand. Plus, the government workers (contract and federal) are usually behind the time in relation to the equipment they have due to the procurement process.
There's a big difference between regular bureaucratic government, and operational defense government. The latter is more military-style, get-it-done. When I saw it they had the latest firewalls, IDS and routers, and some high-speed people to run them. The response I saw to Code Red was fast and efficient, and the network made it relatively unscathed.
Contrast that with local bureaucrat networks, where I Love You took them down by the hundreds. These are the people who set up unsecured wireless, set up wide-open proxy servers, and do all other manner of stupid stuff. They just make the job of the computer security people harder.
