I was DC, and am now DC again. LOL.
But to answer your question, yes and no. Being DC is a lot like being SM in that my role is to know rules/regs, and then empower leaders (only the DC empowers CC, SMs and CMs instead of SPLs). There have been lots of times when somebody wished I could make a difficult decision for them, but at the end of the day, it was their decision as it's their unit. The problem is that councils don't want to get involved in unit spats, and if there isn't a strong and active commissioner corps, unit leaders feel like they are stuck on an island with nobody to turn to for advice.
