What Manning is in is called pre-trial confinement . This is, for all intents and purposes, the same a being arrested in the civilian world for a crime and denied bail, which happens all the time. A number of reviews are mandatory for this to happen, and a lot of people have to agree to it.
If you're just relying on a Firewall to block access to ports you shouldn't have open anyways, then yeah, you don't need the firewall
Ah, but one of the best reasons to have a firewall is that there are so many people that don't. Feel free to bang against my firewall all day or go hit my 2 neighbors that don't even have one and get right in. It's not always about being the most secure, but being in a better postion than the next guy.
