32 in a school zone is way too fast and deserves a hefty ticket.
We have to draw a line somewhere. Argue about the specific mph all you want, but where I live, the school zones are congested. Not only are there kids and busses around, there are people trying to enter/exit the school driveway. Like it or not, there is a public safety concern and the speed limit slows everyone down for a reason.
As far as limits posted according to what "safety dictates", who decides? What is safe for some may not be safe for others. We elect people to run governments to decide.
