This quote seems to apply to a lot of current government policy:
"Any intelligent fool can invent further complications, but it takes a genius to retain, or recapture simplicity". E.F. Scumacher.
"Complexity increases in accordance with the number of people who have time to promote it".
Bureaucrats in the Education Department could learn a lot from those two statements. The Departmental policy for removing graffiti appears to have been made as complex as possible by bureaucrats with plenty of time on their hands, and far removed from the front line; and then foisted on unsuspected Principals who are exceptionally busy, and have to then find the time to read and understand the policies, and then also find the time to jump through numerous hoops when they need something cleaned.
