Ramsey Ramerman, an attorney who represents local government in Public Records Act cases, writes this op-ed about the Seattle Times' editorial on the copying costs bills.
As far as the point he makes about how much it costs local government to provide public records, remember that government (federal, state, local) consumes something like 30% of the economy (it's probably closer to 33% nowadays). We'd like some public records in exchange for a third of everything we own. We'll even pay the actual copying costs.
