Rule by bureacracy may well represent stability but it has its own draw-backs.

1. Structural Violence (Hannah Arendt's term, not mine) -- the inability of anyone interacting with/using the bureacracy to LOCATE someone to actually make a decision that isn't already formatted into the SOPs.

2. Bureacratic Politics -- bureacracies will often pursue their own political agendas completely regardless of the needs of those whom they were established to serve. How often will MI5 do something/allow something to happen just to spite MI6. I assure you that US bureacracies play this game, our CIA folks are often happy at the malf-ups of State and vice versa.

3. The general tendency for bureacracies to hope any non-standard problem and/or cirisis will go away -- do nothing-ism.
