It's tough to make a case that 32 MPH is "speeding" in any circumstance, and up here in MA, School Zones are simply speed traps, i.e., revenue enhancers for the local PD.
Its not tough at all 32MPH in a 20MPH is speeding... its not a difficult case to make at all... its over 1.5 times the legal limit.
You may think they are nothing but speed traps, but around schools here the limit is 15MPH, and honestly it should be. Kids all over the place, no reason drivers should not be driving very slowly and cautiously for the block or two around a school.
