Amazing Events or Common Sense Approach

How did the Legislative Committee Meeting manage to take place this afternoon without the presence of a deputy sheriff? Was the absence of the county executive, meeting was at 4PM she goes home at 3PM, the reason no one felt threatened and people were able to discuss matters in a friendly open manner?
Is it possible that the only reason the expense of having a deputy sheriff attend committee meetings during the day is that it's only during the day that the vindictiveness of some behaviors creates a paranoia that can't be squelched?
